What is a good 45/70 powder for 300gr...

[alank2]

Hi,

Looking to shoot 300gr around 1600 fps which is not full strength for 1895 level loads.

I've been loading n133 for my full power loads, but am looking for something:

1. Cheaper.
2. Meters well in a 550 powder measure.
3. Is at least 50% load density.

Any ideas what I should look at?

Thanks,

Alan

hows about IMR 3031? works good for me

[Crazy4nitro]

I second the IMR 3031,I'm getting an Avg. of 1950's over my Chrono with the Load I use. It STILL isnt a "Max" Load,but I'm Happy with it.
Lotsa Bang...Good times.

H4198 has a nice feel under 330g lead bullets to me.

34-35 grains or thereabouts should put you around 1600fps

[alank2]

Hi,

Any experience with any of these? Trying to get the charge weight down to around 30 gr of something low cost per round:

are you going to be using lead bullets or copper covered bullets?

[alank2]

Hi,

Probably some Speer 300gr UHCP's I have hanging around...

Thanks,

Alan

[alank2]

Hi,

I've been loading them with 11 grains of n320 for a "pistol powder" load of about 1000 fps, but it barely fills the case and I always post weigh the rounds to make sure I didn't double charge...

Thanks,

Alan

[BIGGUNGOBOOM]

If you were going to be using lead then I would say use trail boss, but I dont think that there is any data for copper bullets. Reloader 7 works but gonna be hard to find. any of the IMR's or Hogdon powders have worked great for me. I have never tried any of the V stuff

[Washington,D.C.]

IMR-3031 is not going to measure well in a 550. The straight wall rifle powder I like is AA-2495. It may not meter great either though. For a faster powder Accurate Arms shows AA-5744.

Here is a lot of data from Accurate Arms. AA-2495 is the best I've found in 45-70.

Hi,

That 5744 looks promising, I'll check into it.

Thanks everyone for the help!!

Alan

[Brass Nazi]

5744 is OK vut IMR 4198 is great. I do not know how it meters though.

[MakeMineaP99]

Worst case, you can weigh out the charges as needed. How many 45-70s do you folks load at a time, can't be more than 100 I would guess.

[Brass Nazi]

I load 100 at a time. I still use the T mag to load 45/70.

[alank2]

Hi,

I picked up some 5744 tonight, going to start with 31 grains and see how it shoots...

Thanks,

Alan

[Brass Nazi]

FWIW,

I have loaded some 45/70 using 5744 for my buddys trapdoor. I also use it in my muzzleloader.

[Crazy4nitro]

Dan,
I load 20 .45-70's at a Time .......................................Cause thats all the Brass I Have.
One day when these wear out I will buy a New Bag of 100.

Hi,

I've been lazy about my 45-70 loading lately. I got about 180 of them to load now! I do all the brass prep ahead of time (cleaning, lube, resize, polish) so that when they get on the 550 all they have to do is get a primer, get some powder, seat a bullet, and crimp it. No cleaning any lube off after loading because I polished it off in the tumbler.

Thanks,

Alan

[cohutt]

I load 100 at a time on my 550. The locator buttons are teeny, about 1/8th" across the top.
