Best weight bullet for 300 Black Out Deer LOAD

[brstevns]

What would be a good weight cast bullet to use for Small Whitetail in the 300 Black Out, well really in a 30-223.
Shots 150 yards are less

[Tom_in_AZ]

Needs to be supersonic. One of the lighter weights for sure. 110-125?

A 150 gr flat nose at 1800 fps should work fine. It did in a 30-30 at that speed.
Good hunting.https://uploads.tapatalk-cdn.com/20180821/f8e5b664c43e50de24bcabfdab6b70af.jpg

I have a 120gr and a 150 gr. RN mould as well as the Lee 230. I was leaning to the 150 gr.
Any load information?
By the way, nice looking rifle, Was it hard to get it to feed the 30-30 ?

[Hamish]

br,

If you've got Reloder 7, start at 15.0gr. and somewhere around 15.6-15.8 should be what you're looking for.

I do have a little reloader 7. Do you have any idea as to what FPS would be?

[Texas by God]

The boolit with the biggest meplat would be my choice. Is your 30-223 a fast twist? You may need a hard alloy if so.
My 1916 Spanish Mauser was very easy to make work with 30-30Win.
Tell us about your rifle, please.

In cast a 180grGC works great, 208 j word works well subsonic in my TC 300 whisper. Just don't over push it.

[tsubaki]

With each of my firearms, I generally try to hold to a minimum of 500 foot pounds at the distance of impact. This was the older Georgia State handgun regulations requirements, it works well for the deer in southeast GA.
I’m still playing with the cast in the 300aac.
18.0gr of 2230 is producing just under 1500fps in a 16” barrel with powder coated Lee C309-160-R. Actual weight is 166gr. OAL 1.940” is in the upper lube groove. These were recovered from a dirt pile at a 100 yards

What’s your alloy?

[tsubaki]

I’ve already arrived that Sierra’s 135gr #2124 does fine in the 3 different 300aac firearms I have but it still sticks in my mind something in a 150gr would do a little better. Once I get through playing with some jacketed 150 RN stuff, I may get Lee’s C309-150-F to see how it acts.
I’m trying to keep up to velocities that will expand well enough depending on the bullet used.
A cast one might do it.

[tsubaki]

What’s your alloy?
It is an unknown alloy, X-ray room lead, wheel weights, etc.
Best I remember it is about a BHN11 hardness.

[cwlongshot]

I like the heavier slugs. 170-180 But the 150 RN I have is also a favorite in my 32-20 so should be great in the 30-30 too.

I agree taylor the mix and watch the velocity/pressures.

Good luck,

For hogs I use a 145gr PB (31-142C) @ ~ 2k fps. MOA @ 100 & 1k #-'. Working with a 170 PB & 185GC (31-184C) I did for 30/30 but works good in BO. Actually shot the 10" 1:8 pistol today @25, even the soft alloy did pretty good, Just a sightmark holo .You got more case in apache so 335 might work.

[Drm50]

I have found the Speer 130g HP to preform well out of 30/30 & 300 Savage. I found this bullet by
accident when a buddy bought a M1a. The booklet that came with it suggested it as accuracy load.
I shot them out of a Marlin Marauder 16" barrel and shot some 1" groups at 60yds. It's pointed
bullet so I put one in chamber & one in tube. I have shot a couple deer with this bullet and it
expanded nicely. My longest deer kill with a 30/30 was made with this bullet, 150yds.

X Ray lead is close to pure if I remember which explains the awesome looking mushrooms.

[quilbilly]

I have a 7mm TCU carbine (basically a 7mm/223) that has done the job on our local deer with 140 gr. boolits at an MV of about 1700 fps including a couple over 200# on the hoof. Ranges have been 100 yards or less. All have been pass throughs with a large exit wound. My alloy is 2/3 pure, 1/3 hard birdshot with some extra tin added.

[KenH]

in the 300 Black Out, well really in a 30-223.

There's a lot of difference in a 300BO and a 30-223. Which is it?

It is the 30-223, just hard to find loading data.
Thinking about using 7 tcu data.
Have a Savage Axis that has been rebarreled to it. Barrel is 17 1/2 inches with a 1-10 1/2 twist.
Rest in a Boyds stock.
Nice little bush rifle.

OK, I was confused (easy for me) since your subject had 300BO listed. Then down in the body you listed the 30-223.

The 30-223 is a new cartridge to me - that would be a good round. Actually better balisticaly than the 300BO. I think I like the sound of the 30-223.

Good luck.

[popper]

Just a longer BO. Looked at x39 data yet?

The 7.63x39 data I would think would be on the hot side?

[popper]

Case volume about the same. You could go with slower powders too.

Good luck.I like the sound of that too, I already have a BO, 308, and 30 06...I can with those load a whole range of uploaded or downloaded rounds for the range of stuff...cant justify the cost to rechamber and retool for another round they would split the difference between 300 BO and 308 for me....but all that to say it sure is tempting to try and find a good reason!

I love tinkering, making brass from range pick up and the like

What is the case volume of both?

[John McCorkle]

Not sure why I didn't think to drop this in before but there is a group buy on a hollow point mold that may be perfect for 300 Bo

You measure volume of the case full of water, usually with a syringe. Used to have a table on the computer but can't find it now. One approach is to seat a dummy and fill through the primer hole. It will vary a bit but if they are close (40WT is supposed to be close performance wise) you can try start loads for the other cartridge. You also need to verify same book pressure and evaluate if your gun can take it.

From what I can find. The 7.62x39 holds 4 gr more . So roughly 1/10 more water then the 223 brass

[Time Killer]

Go to Mad Dog Weapon Systems web site. They have a whole listing for the 7.62 X 40 (Or 300 BO Magnum as I like to call it). I would recommend a 125 gr jacketed or 130 -140 gr lead bullet for that caliber as bullet length becomes an issue with this one. Have the 7.62 X 40 myself but have not got the loads worked up for it yet. NOE has a 130 + grain mold that I love in the 300 BO. I am hoping that it works well in this one to.

[popper]

30/223 is longer than 40wt. 150ish boolit with 40wt start loads should be good.

[brstevns]

Looks as if 20 gr of 1680 with some 150 flat nose should give around 1800 FPS from my 17 1/2 inch barrel.

[tsubaki]

I'm actually getting 1870fps in a 16" barrel using 19.0gr of 1680 with Remingtons 150gr PSPCL.
One of the 150gr 30-30 bullets are to be my next tests.

That is great to know. I am going to be using some old Herters 150gr FP 30-30 bullets that I have had stored for years.

[cwlongshot]

1680 Is a great powder for +150G in the lil 300.

I have an old article by Roy Dunlap IIRC about the 30 Apache which is 30-223. He listed several loads for "J" bullets that may be of use. PM me if you'd like a copy or I can post.

Longbow

[longbow]

Okay then here's what I have:

226289
226290
226291
226292

Not as much reloading info as I thought I had in the Roy Dunlap article. There is a bit more in the Elgin Gates copies from Metallic Silhouette Shooting but again not a lot.

At one point I was thinking of going this route myself and I am sure I had more load data collected but am not finding it where I "remember" I put it!

Oh well... it may still be of use to you.

[Bigslug]

I'd be looking at this puzzle thinking that you're basically playing in .357 Magnum territory for bullet weights plus a bit extra in the speed department.

Quenched wheelweight gave me nine milk jugs of penetration with an aggressively flat-nosed 130 grain .32 at 1250 fps, so I don't think you need to have concern over a non-expanding 125-ish grainer failing to make it to the Tootsie Roll Center of the Tootsiepop.

If you can get full Blackout supersonic velocity with accuracy out of your alloy, I'd say go for max speed with lighter, gas-checked slugs. If the accuracy degrades at speed, and you have to go slower, up the weight to better hang onto what speed you can generate.

[Texas by God]

I haven't been happy with the accuracy of cast in my .300 Blackout so if I do use it I'll go this route.https://uploads.tapatalk-cdn.com/20180829/663748e449dfee6c41af9ff98056884e.jpg

I got slight tipping with 175gr PB cast from a 1:8 pistol. Your 1:10 may need to go faster. H4895 down loads good and I've heard of it's use in BO. Your case capacity is larger so the slower powders may work better. H335 is normal for 223 but it doesn't download as easy.

I have taken two deer with that Speer 130FP in the BO. First was about 25 yards bullet deflected off a 2" tree but still took out a rib, did much damage in the liver and was found in the ham. The second was thru and thru getting a rib both sides IIRC. Showed expansion but not violent. its a tough bullet for the blackout. Wont over expand is what I mean. My vel is right at 2K on a chrono.

[Moonie]

I've just loaded some 125gr Nosler AB's for hunting this year, if I decide to use the 300 for that.

[brstevns]

Tried a few rounds of 150gr Herters FP over 20gr 1680. No signs of pressure.

Range report... expansion test

Just shot a couple potential deer loads into milk jugs with water (not the best test media but cheapest and not the worst either)

Lee 312-155 2r sized .309 with gas check of quenched coww...over h110 with 1890 fps and 1927 fps...

First shot penetrated 1 qt carton, 2 1/2 gal cartons and one full gal piercing 2nd gal (caught in first gal) at 1890...pic below. As cast was 160 grains and with the piece that shed weighed in at 156 grains

Second shot penetrated 2 gal jugs and turned south into 6 inches of berm...@ 1927 fps still weighed 158 grains

Excited about this load as it performed much better than expected.

Also shot two Speer 130 fp at 2130 fps (very warm) but recovered neither...judging exit holes and apparent damage it will do fantastic... penetrated 3 full jugs each and caused enough force in the other side to clear all the leaves with just the force of escaping water...blew an empty jug 2ft into adjacent undergrowthhttps://uploads.tapatalk-cdn.com/20180905/17bde81187ea301e9838be2181d08d53.jpghttps://uploads.tapatalk-cdn.com/20180905/5009b560ccc99b51e85009a41f8a1fba.jpghttps://uploads.tapatalk-cdn.com/20180905/b3fb2011e7aa190949c25ae6333f85d6.jpg
