I've used Elmer Keith's load of 53 grains of 3031 with a 405 grain jacketed bullet and had good results. In fact my sons and one grandson a going on an Alaska black bear hunt this week and one will be useing that load in his guide gun.

IMR3031 is the cats weow in the 45-70. I even use it with paper patched bullets, and I also use it in my 30-30.

47 gr IMR 3031, Rem Brass, Win LR Std Primer and Rem 405's, has shot 5 shot groups under an inch @ 100 yds in my 1895CB. I thought the first time was a fluke untill I did it two more times. Get about 1650 fps with that load.

It will depend on your rifle, the brass and boolit in use.

With my RUGER#1, I can not seat the boolit to the crimp grove and get anything like a decent load in the Starline cases.

Bruce from BRP Products, maker of great boolit molds, says that Winchester Brass will hold quite a bit more powder then the Starline brass.

I have some loaded for tests, but I start running into seating problems with the 3031 before teaching 48gr.

Keep em coming!

3031 was about all I ever used until I started with the warmer loads...I like the temperature stability of H322 for the warm loads.

The burn rates are very similar...

3031 is a good powder for the 45-70 (has been for me). I've posted it on marlinowners on other threads, but I use 50 grains IMR 3031 with a Remington 405 grain jacketed bullet, and get well under 2.0 moa accuracy (more like 1.25++). Rifle is a ballard-rifled Marlin 1895, with 22" bbl.

I tried the oft quoted "Elmer load" of 53 grains of IMR 3031 over the Remington 405 grain jacketed, but I got sticky extraction from my Marlin 1895 45-70, and settled on 50 grains. I don't have a chronograph, but I'm guessing the MV is 1650-1700 fps. Plenty of oomph for any white tail I'll see in Maine. I could go to 51.5 grains of 3031, but 50 grains was more accurate-and easy to remember.

Other shooters on the board have tried the 50 grain load of 3031, and have largely reported excellent accuracy with just about any bullet up to 400ish grains. That's good performance in my book.

This is very interesting, but before I try it I am shooting a Pedersoli Sharps and a NEF Handi rifle and I will need to know the pressures. The two powders that I am using (with very good accuracy from both) are Varget and Trail Boss.

Thanks

Correct me if I'm wrong but, wasn't 3031 developed for the .30 Winchester cartridge?

Probably was, but that doesn't mean that it is not good for other cartridges. ;)
