Typhoon F12 Sabot Slug Loads?

[Armilite]

I Read a Standard 1oz 12ga Slug can travel about 5500 ft = 1,833.3 yds. If Sighted in for 100 yds it has a 10"-12" drop at 200 yds depending on Load fps. With that said. I want to develop a 12ga Slug Load for my New Typhoon F12 I got from the Wife for Xmas. Also got a 4x32 Scope with Range Finder.

3/4 oz = 328.125 gr
1.0 oz = 437.5 gr
1.125 oz = 492.1875 gr
1.25 oz = 546.875 gr

IF, a Lyman 12ga Sabot Slug is supposed to be 525 gr = 1.2 oz!

My Questions:

1. Is the Lyman 12ga Slug 525gr made with Wheel Weights, or Lead Pipe or Plumbers Lead, etc?

2. Has anyone used this 12 Gauge Sabot Slug Bullet Mold Svarog Match (Lyman style)?

3. Wheel Weights are the easiest to find. With a Lyman Sabot Mold, what does the Avg Slug Weight made with Wheels Weights?

4. Since it's a Semi-Auto 12ga, what are the Cleanest Burning Powders?

[Armilite]

A Comparison I found on the web of a 12ga Slug Sighted in for 100 yds, vs a .30-06, 9mm, .45ACP! Slug 10"-12" drop at 200 yds, about 4ft at 400 yds.

Does anyone know of a web-based Ballist Calc like this?

[megasupermagnum]

I Read a Standard 1oz 12ga Slug can travel about 1750 yds. If Sighted in for 100 yds it has a 10"-12" drop at 300 yds depending on Load fps. With that said. I want to develop a 12ga Slug Load for my New Typhoon F12 I got from the Wife for Xmas. Also got a 4x32 Scope with Range Finder.

#1, wheel weights can work, but this is one area that a softer slug may work better. I've heard reports that too brittle an alloy can crack the skirt, ruining accuracy. Lead pipe or Plumbers lead would work great.

#2 I have not used that specific mold, although a number here have. I have used the slug though.

#3 I don't remember the exact weight of the slug with the alloy I used. I can check later.

#4 I wouldn't worry about the cleanliness. Unlike brass loading, shotgun loading data stops at a specific velocity, rarely to max pressure. There is lots of good powders with data at low pressure that burns dirty. If at a higher pressure, many powders are quite clean. I'd pay more attention to which loads are over 10,000 psi if looking for cleanliness.

The ballistics you state are false. That would likely be the trajectory of a 30 WCF round. A standard 1 ounce rifled slug sighted at 100 yards, you are looking at about 33" low at 200, and 117" low at 300 yards. I calculate that fired at an ideal angle of 30 degrees, they would travel 1170 yards before hitting the ground.

[Armilite]

Projectile Ranges. Notice a 1 oz Slug 5500 ft = 1,833.3 yds at 12,000ft, at Sea level you're still looking at 3,750ft = 1,250 yds!

[megasupermagnum]

Projectile Ranges. Notice a 1 oz Slug 5500 ft = 1,833.3 yds!

Yeah, if fired on top of a mountain at 12,000 feet. At sea level, that graph shows about 3700 feet AKA 1233 yards. I can also tell you that graph is optimistic. I'm at about 1300 feet above sea level, and #7.5 shot only goes 225 maybe 250 yards tops. I really doubt a #4 is going to go about 350 yards as that graph predicts.

[megasupermagnum]

I just checked the weight of my Lyman slugs. I bought them from GT bullets, they use an alloy of 96-2-2, which is slightly softer than COWW. They average about 512 grains.

========================================

1. IF, too brittle an alloy can crack the skirt, I would suspect the Mold not being the right Temp when the Lead was poured in. I have seen that in many Pistol & Rifle Bullets.

2. I have only Loaded 12ga #6 Shot and OO Buck, and that was 15 years ago. My friend has a Mec Loader so I reloaded a bunch up 500+. I used Unique Powder and made Magnum Loads.

3. The Test Photo says, 12ga 1oz Slug, .30-06, 9mm, .45ACP. A 1oz Slug can be loaded at many different fps Velocity's so Slug Drop will vary also. Then you got 2-3/4" vs 3.0" vs 3-1/4" Shells. I'm mainly interested in 2-3/4" Shell Data. I got 750 AA Hulls coming.

I found this Data on Hornaday 12 GA SST® Slug 300 gr = 0.6857143 oz. Pretty Impressive.

[megasupermagnum]

The skirts on these slugs and many others are weak. That is a good thing, as it allows them to bump up to the right size. COWW's might work, but definitely nothing harder than that. Unique powder would be a good choice for these slugs. The muzzle velocity is not going to have a monumental impact on how far or flat they fly. Even comparing 1200 fps to 1600 fps doesn't amount to anything much worth talking about. Those Hornady SST slugs are impressive on paper, but suck in the real world. The old load shot good, then Hornady pulled the rug out. They haven't shot good in over 10 years, and I don't know anyone who likes them. Your gun is a smooth bore, and many of those sabot deer slugs are only stabile from a rifled barrel. A high velocity slug that often shoots very well from a smooth bore is the Remington 7/8 oz slugger at 1800 fps.

What was the difference between this Old Load vs the New Load you're talking about, Grains, FPS?

Thanks, I'll check out that Remington 7/8 oz slugger at 1800 fps load. Does anyone make a Mold for them Type of Slugs?

Yes, the Typhoon F12 is a Smooth Bore, but you can get Rifled Chokes which should tighten your Groups. Hornady's website does say the 300gr Slug is for a fully Rifled Barrel. Your assumption that "1200 fps to 1600 fps doesn't amount to anything much worth talking about", is Flawed.

100 Count ( $26.95 ) (8 lbs) $26.95/100 = 0.2695 each! Plus $8.75 Shipping! I Ordered these to try!

250 Count ( $65.00 ) (19.25 lbs) $65.00/250 = 0.26 each! Plus $15.50 Shipping!

500 Count ( $125.00 ) (37.75 lbs) $125/500 = 0.25 each! Plus $15.50 Shipping!

"Cast lead Lyman Style 525gr Slugs for loading in a sabot / Wad for 12 gauge shotguns. Best used in rifled barrels or using a rifled choke. They are cast from 2-2-96 alloy."

So Buying that 12 Gauge Sabot Slug Bullet Mold Svarog Match (Lyman style) for $98 with Free Shipping would Pay for itself really fast.

Lead 1lb = 7000gr/512gr = 13.7 Slugs per Pound. 750 Cases x 512 gr = 384,000gr/7000 = 54.9 lbs of lead needed.

Is there a Prefered WAD to use these Type of Slugs?

Armilie,
In the real world, there is a lot of truth in this statement. Overall, deer hunting is a short-range endeavor. In most places, a 200 yard shot at a deer just isn't possible. Two hundred yard accuracy is possible, but, IMO your time is better spent finding an accurate 100 yard load, learning it limitations, and hunting within those limitations. You're free to do as you wish but be careful which rabbit hole you dive into! This is a rewarding hobby and has a lot of built-in frustration that comes with it.

I have no idea what changed, trade secret. If I could ever find a real old box of them, I'd love to cut them open and compare. Even from a fully rifled barrel, it seems most guys are doing good to shoot 3-4" groups at 50 yards with the new SST.

Lee makes a 7/8 oz foster slug mold.

A rifled choke is worth a try, but it is not guaranteed to increase accuracy. Don't even worry about velocity. You are not going to get accurate loads your first try. It is doubtful that gun will ever be accurate enough for any real use beyond 100 yards. If a smooth bore shoots 3" at 50 yards, or under 8" at 100 yards, you are doing very good.

The Lyman sabot slug is a great place to start. They fly great from a smooth bore, but a rifled choke is worth a try. Since you bought AA hulls, I would recommend the 1 1/4oz Winchester WAA12F114 wad. Buy the Winchester brand, not a clone like Claybuster. This wad will work with Unique, Universal, WSF, and Herco powders. I would suggest you start with the Unique load, which should burn good and clean. All loads are listed with Winchester 209 primers, do not swap primers. You will need to get the Lyman shotshell reloading handbook for data. You will also want 18 gauge nitro cards for under the slug. 20 gauge will work too.

=============================

Centershot, maybe in your little speck of this Big World you might only have a 50-100 Yard Shot, but don't lump the rest of the World into your limited hunting possibilities! Shotguns, as well as Pistols & Rifles, are used for more than just Deer Hunting. In IOWA, which most of it is wide open Corn, Bean, Hay Fields, you might want to or have to take a 50 to 300+-yard shot. Your limitations and choice of Accuricity needed can be way different than other people in this world.

The Higher the Velocity(FPS) the more Energy (FT.-lbs) you have to play with, which also means less Bullet/Slug drop.

I'm 64 years old and in my experience of Hunting, Reloading, Target Shooting, I have learned one thing, most people can't shoot worth a darn, mainly account they don't practice enough and they set limitations. I use to shoot 1000 rounds a week when the weather was warm. Today, we have Indoor Ranges popping up all over. Like one day I was at the outdoor range and had just gotten done setting up some Orange Clay Pigeons at 100 yds and was 3/4 of the way back when a guy drives up and gets out and starts unloading his rifles and asks me what are you shooting, I say, I'm Shooting my Browning Hi-Power, and he says at what looking downrange? So I turn and say them Clay Pigeons at 100 yds. He scoffed and says, I'll have to see that. So I turned and loaded a mag in the pistol and shot 5 for 5. He was amazed. He says wow, I only shoot my Pistol out to 25 yds because I "read" where most shots are in less than 25ft. I said, what if the guy is at 50yds, 75yds, 100yds! A Sten MKII WWII 9mm (Muzzle velocity 1,198 fps) and (1,001 fps suppressed models) Submachine gun, has a 100m = 109.4 yds effective range, the Thompson M1A1 in .45ACP (Muzzle velocity 935 fps) and had an Effective firing range of (164 yds = 150 m) with a longer Barrel. The moral of the story, don't set limitations on yourself or your Firearm.

2nd story. I'm at the other 250 yds outdoor range one day with my 22-250 Varmit Rifle with my Spotting Scope and a pair of young guys pull in with a New AK47. Each shoots a mag at close range 50 yd, then 100 yds to sight it in, then they want to see what it will do at 250 yds. I agree to spot for them with my Spotting Scope. Nither could make a Good Group at 250 yds on a 2ft x 2ft Target. Of course, I'm snickering over there as I'm spotting them. Finally one of them asks if I want to shoot the AK, maybe I can do better. So I say, yea, I have shot about every type of gun, and owned about 65 at one time, but not an AK. So I have one of them spot me, and I shot 5 rounds at 250yds in a 5 inch Group with Iron Sights. I hand it back and tell them it's not the gun, it's their shooting.

Remember that Alaskan Bear that charged and ate the Hiker who had dumped (4) shots of 44 Magnum into its chest, and then the next day it charged a Forest Service guy out Deer Hunting who then shot (4) 7mm Magnums into it before dropping it at his feet.

FPS and Energy are always Important, whether it's a Shotgun, Rifle, or Pistol, round.

Example: "A .30-30 rifle firing a Federal factory load with a 150 grain bullet at a muzzle velocity of 2,390 fps. At the muzzle, that bullet carries 1,900 ft. lbs. of energy. At 100 yards the energy has fallen to 1,355 ft. lbs. At 200 yards the energy is down to 945 ft. lbs. At 300 yards the energy has fallen to only 650 ft-lbs., which is below our 800 ft. lb. minimum. The velocity, by the way, is down to 1400 fps at 300 yards. One could conclude that the .30-30 is about a 200+ yard deer cartridge, based on its energy, and one would be right."

That 12ga Hornady SST 2000fps 300gr Slug is still making 841 lbs of Energy at 300 yds! If sighted in for 150 yds, you have a Bullet drop of -35" at 300yds. With a Good Scope with Bullet drop lines that ought to achievable.

[W.R.Buchanan]

OK let me put in my .02 here. I agree with your theory of limitations,,, mostly. However you have got to know what the limitations are so that you can effectively deal with them when you are out on the edges.

My Lyman Slugs are cast from WW since I have lots of it. They weigh 504 gr or 512 gr when the base is filled with Hot Glue. Don't bother with the Russian Mould just get one from MP moulds as they work alot better and make perfect slugs right out of the gate.

https://www.mp-molds.com/

Some here have gotten <3" groups at 100 yards with the Lyman Slugs, with scope sighted rifled barrel shotguns, So far I have only been able to get <2" at 50 yards, but I only use Open Sights on a Rifled Barrel.

I have other slugs that perform better.


I can see shooting at 200 yards with a 12 or 20 ga. Rifle like a Savage 212-220 or a TC Encore. and there are others that could consistently do it. (Look at Tarhunt Rifles)

But a Generic Shotgun. Even with a Rifled Barrel is going to be hard pressed to do ANYTHING TWICE IN A ROW at 200 yards.

But the weak link here is going to be your ammunition and the Lyman Slug is not going to be at the top of the charts. They were designed to be <100 yard projectile and for that, they generally work OK, however they are a Slug with a 3/4" flat nose so the aerodynamics are not all that, and then add any imperfections in the slug which worsen it and you reliable range is only decreasing.

Lightfield Sabot Slugs are at the top of the heap, and there is plenty of videos that support this. There is one on Youtube that has some guys shooting Deer at 300 yards with a Savage 220 with Lightfield Slugs. However they are shooting over bait and have the trajectory sussed out carefully for that exact distance. They are essentially lobbing rounds in onto a target. +/- 15 yards and they'd miss.


The one thing I do agree with totally is that the vast majority of shooters can't shoot, and their limitations by default are greater whether they know it or not.

Practice can be used to hone your skills but you can only go so far with certain types of equipment until you run into a road block. So knowing the limitations of you and your equipment is key to success.

A rifled choke is worth a try, but it is not guaranteed to increase accuracy. Don't even worry about velocity. You are not going to get accurate loads your first try. It is doubtful that gun will ever be accurate enough for any real use beyond 100 yards. If a smooth bore shoots 3" at 50 yards, or under 8" at 100 yards, you are doing very good.

The Lyman sabot slug is a great place to start. They fly great from a smooth bore, but a rifled choke is worth a try. Since you bought AA hulls, I would recommend the 1 1/4oz Winchester WAA12F114 wad. Buy the Winchester brand, not a clone like Claybuster. This wad will work with Unique, Universal, WSF, and Herco powders. I would suggest you start with the Unique load, which should burn good and clean. All loads are listed with Winchester 209 primers, do not swap primers. You will need to get the Lyman shotshell reloading handbook for data. You will also want 18 gauge nitro cards for under the slug. 20 gauge will work too.

================================================

Did you ever write to them about the round?

Ok, Thanks, I'll check out the Lee 7/8 oz foster slug mold. I got a lot of Lead on hand 250-300lbs. So I would like to Cast a Bunch up. A fellow on Youtube showed a Test, with and without the Rifled Choke. It made a difference. I ordered a Small Batch of them Lyman Slugs to try. The Shelves around here are Empty of almost all Ammo, Primers, Powder, and Wads, and Guns. I'm sure I got a Lyman shotshell reloading handbook, but it's old. I got some Wads from a long time ago, I have to clean the GUN room and see what I all got for 12ga Reloading.

I found about every size of these "You will also want 18 gauge nitro cards for under the slug" but 18ga.
https://www.grafs.com/catalog/category/categoryId/408

Product Overview:
Nitro Cards were originally used by black powder shotgunners to seal between the powder and the shot. Today they are used as a fine-tuning spacer wad inside the shot cup. Use 12 gauge in a 10 gauge shot cup and 20 gauge in a 12 gauge shot cup. .125" Thick.

Notes:

Nitro cards are used as a seal between the powder and the shot.
They can be added to any modern load where the shot cup is sitting too low for a proper crimp.

Hello Armilite, Hornady played a very dirty trick on us unsuspecting shooters with their 12ga Hornady SST 2000fps 300gr Slug thay had very high pressures and not safe to shoot in older guns.
The warning is hardly visible and they have the money, lawyers to get away if one gets hurt or killed !
"For a weapon proofed by 1370 bar MAX 1050 bar".
I have seen charts that show typical 12 ga barrel service pressures are at 11,500 psi.
But 1370 bar = 19870 psi and 1050 bar = 15229 psi,

Its a race with the devil trying to sell us their own product while keeping our life in danger !
They have the money to hire the best lawyer to cover up.

I fully agree with Centershot's statement above.
Most deer are shot under 40 yards and that too could be considered a long shot.

Happy New Year to all our friends here.

WILL A RIFLED CHOKE IMPROVE ACCURACY WITH RIFLED SLUGS?
https://www.youtube.com/watch?v=PzWKjhWyxpw&t=552s

DGS slugs are manufactured by Gualandi of Italy, are suppose to be Good also.

[longbow]

I have never had ACWW or even oven heat treated WW crack at firing. ACWW is soft enough to deform some and I know it can crack if worked too much because when I made a sizer to take the taper out of my Lee slugs cast from ACWW they broke up after a certain amount of sizing. I had to open up the sizer to stop the cracking/breaking from work hardening. I don't quite get all the taper out now but close. No matter that didn't result in what I wanted anyway.

I have oven heat treated thin skirt HB slugs because ACWW was distorting at firing (skirts were belling) and the oven heat treating solved that and accuracy improved but terminal performance was not so good as the slugs broke up in the berm due to being too brittle.

I have had ACWW slugs with 0.100" skirts deform at firing too which was a bit surprising. That's one of the main reasons I went to solid attached wad slugs instead of HB slugs. Still trying to clone AQ slugs! More or less anyway. AQ's aren't truly solid but they are very thick skirted just to allow plug in tail wads.

Closest you will find to 7/8 oz. Slugger is likely the Lee 7/8 oz. slug which is a wad slug or for full bore these guys but the lightest slug mould they make is for 36 grams or about 1 1/4 oz.:
