Wanted----Subsonic 45-70 loads

Charmedlyfe · November 22, 2000, 10:13 PM

I'm working on a project- a 45-70 tactical rifle to be supressed. I'm looking for 500-yard range, and a 400-500 grain bullet. Any help on loads? It's a bolt-action (Mauser 98/Siamese blend)with maybe a 20 to 26" barrel, based on what is shortest with best velocity.

George, please fill me in on your Siamese Mauser .45-70 project, I've got a Siamese action that is sitting in a drawer waiting for the right smith to build it into a .45-70, but those guys are getting fewer and farther between. I had in mind a Mannlicher-stocked variant, with octagon barrel, browned, not blued, with one of those vintage brass scopes ala' Navy Arms, sort of a "what-if" turn-of the century .45-70 bolt rifle. I've already made up loads for it, with a 405gr cast flat-point bullet, bought a ton of new Remington Nickel brass, and there the project stalled...

My favorite 'smith (and a good friend) did some research when I was planning this beastie, and found that the only Siamese parts you really need are the bolt and triggerguard. So, we're using a VZ24 receiver with those Siamese parts. Also, makes cutting the barrel threads easier. The guy is a genius when it comes to Mausers specifically, and rifles generally. I've got a VZ24 in 308 that we built, and it shoots 1/2moa all day long.

I thought that, since the 45-70 is such a slow mover already, subsonic would just be a short step. A 500gr. bullet would be durn near impervious to wind, I'd just need enough elevation. Further, I could also shoot 45-70 Ruger loads if I so chose.

COuldn't you start with the loads for the trap door springfields?They only moved out at about 1350 with a 405 grain bullet.Shouldn't be hard to just download a little bit from there to get subsonic.
Just an idea.
My Complete guide to handloading by Sharpe gives a couple loads that might work for you.
405gr lead unique 11.0 1133
405gr lead unique 17.3 1472

500gr lead unique 11.0 1020
500gr lead unique 17.2 1330

All the rest of the loads use powder no longer made.
Hope this helps

The above url leads to a piece on 2 gr. of Bullseye behind a button bullet.

The above url sells the 155 gr. 45/70 bullet.

With my very short barreled 45/70, subsonic gas behind bullet is at about 1/2 gr. Bullseye, and I use a .457" soft lead ball, that wieghs about 150 gr.

If you have a supressor, then I guess you don't care about keeping the gas subsonic, that is the surpressor's job.

Makes me wanna go out and buy an NEF Handy Rifle and a Marlin Guide Gun both in .45-70, and start load development!!

(sigh)

On a cop's salary? I'm looking at Christmas.
