Midrange 454

[High Desert Hunter]

I am looking for powder ideas for a 340gr WFNPB bullet at 1200-1400fps, more in the 12-1300 range. Right now I am using HS6 and Unique, but I am running low on HS6, and Unique isn't really good for those kind of velocities with the heavier bullets. I have been experimenting with 2400, but it too seems better for the lighter weight bullets.

i had the best luck with H110 for the 300gr boolits

[High Desert Hunter]

I use H110 for my full throttle 454 loads, but I won't go near the bottom loads with H110.

[gknarf]

4227 would work

[High Desert Hunter]

Someday I hope to be able to find some!

[dh2]

W296 is about the same as H110 and I have been able to find it when there was no H110 to be found

Give Lil Gun a look bottom loading looks to be in the range you are looking for.

[44man]

Twist is slow for the heavy boolits. They need shot faster. The 1 in 24" rate was made for speed.
Max load of 296 should do it.
The guns don't like Colt speeds.

AA#7, AA#9 or Accurate Arms 4100/Ramshot Enforcer (same powder) is also another good one. I have 10 to 11 pounds of 4100/Enforcer and have really taken to the powder for what you are wanting in the 454.

A person can get good accuracy with a 300-350 grainer starting at 1200 fps and gets better as you one goes, even with a 1:24" twist. My SRH 454 with a 7 1/2" barrel shoots 1 inch groups at 30 yards open sights at a bit over 1200 fps with the two LFN style designs I put together. I mostly shoot my 345 grainer out of the SRH and then the 310 grain in the Bisley BH.

For loads in that velocity level of 1,200 to 1,300 fps HS6 is my choice also, if not try a powder in the same burning speed as HS6.

For loads in the 1,000 to 1,100 fps range i use 8.0 to 9.0 grs Tight group powder with excellent results.

For loads in the 1,450 fps range i have had excellent results with 28.0 grs of 296/H-110 and 26grs of WCC 820

W296 is about the same as H110 and I have been able to find it when there was no H110 to be found

W296 and H110 are the same powder with only lot to lot variance.

[High Desert Hunter]

I get good accuracy with bullets up to 360 grains as low as 900fps, my 45/70 has a 1:20 twist and stabilizes 550gr bullets at 1000fps. Long range the WFN designs tend to destabilize quicker than the LFN or SWC do, but even the big 360s are still stable at 150 yards, no keyholes. Right now I am almost out of HS6, which is what I have been using, and being in the middle of nowhere, my LGS hasn't gotten a powder shipment with pistol powder in months. Keep the suggestions coming, if they get a shipment in, I don't want to over look anything, my Freedom Arms gets hungry!

If you want to know what twist rate you need, here is a good calculator http://kwk.us/twist.html , length of bullet is the critical measurement, a 1:24 twist will stabilize a 1" bullet, the smaller the bore diameter, the faster the twist rate, now, as in the case of the 22-250 vs .223, you can use velocity to overcome some of the lack of twist rate. Every gun is different, but this formula has worked for me.

[44man]

No formula works, Greenhill the worst ever. The .44 Marlin is based on Greenhill with a 1 in 38" twist, what an abortion!
Want to see what a 45-70 will do with around 300 to 440 gr boolits, Get a BFR revolver with a 1 in 14" rate. 1 in 20 in a rifle is too slow and 1 in 18" is borderline. A rifle should be 1 in 16".
Every single twist thing I ever seen is too slow. Nobody has ever got it right.
I just used that site and got a 1 in 32" twist rate for my .475 BFR. ARE YOU KIDDING? Mine is 1 in 15" and has done 1/2" at 100 yards. 4 out of 5 on a 6" swinger at 400 yards after the first sighter. Yeah WFN boolit too.
No revolver maker in history has gotten twist rates better then Magnum Research. In the big guns, Freedom, Ruger and most others are wrong. The .454 should be 1 in 16". The .500's should be 1 in 15".Attachment 122060 The hole in the top of this can is 5 shots from the BFR 45-70 at 100 yards. A friend did the other damage with an ACP rifle.
I shot a can at 200 yards with my .475, Creedmore and put it up at 100 and shot it off hand. Same stinking hole.

I use BlueDot.

[High Desert Hunter]

My 45/70, with a 1:20 twist, and a 525gr bullet, at BP velocities will shoot MOA out beyond 500 yards, my 454, with the 1:24 will shoot 2 MOA out beyond 200 yards at 45 Colt velocities, and I have made hits on a plywood target set up for rifles at over 400 yards with 335gr bullets at 1200fps, and the bullets were still flying true. I think each gun is a rule unto itself, and while the twist calculator hasn't worked for you, it has helped me over the years. I was shooting the heavy 390s from my 454 15 years ago, and never had any issues. I am no Elmer Keith, and I'm nowhere near your class of shooter, hands and eyes won't allow it, but for my ranges, and the bullet weights I shoot, I have yet to have a single issue with my 454 out to 200 yards, and 99% of my shooting is 100 yards and in. I have even shot a sized down 412gr 45/70 bullet in my 454 at around 1K fps, and was very accurate at 50 yards. 454PB, I used to use a lot of Blue Dot, but I don't think I have seen a pound of the stuff in 2 years, it works very well in the 44 and 454. Have you tried AA #5 or #7? Just curious, I want to be able to buy anything that will work if it shows up. I may have to take a road trip to Albuquerque to see if Sportsman's Warehouse has anything in stock. I have plenty of Unique, just I am about tapped out of HS6 and 2400, which have been my midrange utility powders. I appreciate the inputs, and 44man, I know your feelings on the twist subject, and I generally defer to your experience, but in this case, personal experience has shown me different, not saying you are wrong, just know in my guns, what works, and has worked for a few years now. I bought a 454 for 325s-345s at 1500fps, years later, I'm glad I can shoot it with reduced loads, as the years of being an Air Force aircraft mechanic haven't been kind to my hands. Thank you again for the inputs, I at least have a list that is growing.

This is a good article on the 44, and when I read it, I was surprised by the ability of the Marlin 1894 with a 1:38 twist to stabilize bullets over 300 grains, quite contrary to what I have read, and the main reason I didn't jump on one when I had the chance. There are a bunch of great articles on this website.

[44man]

Not to be with the Marlin. Sorry, does not work. So much is wrong I gag.

[High Desert Hunter]

I would sure like to wring one out with my 310gr RNFPGC bullet, shoots so good from my Super Blackhawk it's scary, like to just see for myself how well it does in the Marlin.

[454PB]

Way back when I discovered how versatile BlueDot was, I stocked up with several 5 pound kegs. Mine is Hercules. I've used it in everything from 9mm to 45/70.

For .454 loads, the combination I use closest to what you seek is:
Lyman 452651 GC cast in WW alloy, sized .452" weighing 330 grains
16 grains BlueDot, CCI 400 primer.

I own four .454 Casulls ranging from a 4 3/4" FA83 to a Puma model 92 rifle, so the velocity of this load ranges from 1200 fps in the short barrel to 1500 fps. in the long barrel.

I should also mention that I have increased the charge weight experimentally, but will not post those results here in the interest of "internet safety". The 16 grain loading was my starting point.

I can't discuss stability issues because I've had none, limiting my distances to under 100 yards.

I guess you could throw in Alliant Steel as well but metering it through a powder measure can be a PITA. I've load many rounds with this powder and it works very well. However, the only powder measure I've found that works consistently is the plain Jane, Lee auto disk powder measure with the square hopper that I cut out the baffle. Very stable powder but it isn't easy unless you have a dedicated and modified powder measure. I've even used Steel in heavy boolit 45 ACP +P loads with nice results and only a few unburnt powder flakes here and there. Similar to Blue Dot but doesn't seem to burn as hot.
