Karl, you might get more info in the single shot forum as there are more 45-70 fans there plus a lot of Ruger #1 shooters.

What was that Jim!?

NO! NO, YOU CANNOT USE A 45-70 FOR DANGEROUS GAME. PERIOD!

Cheers,

On the other hand you don't REALLY need any load data because the 45-70 is such a effecient killing machine all you have to do is blast a few tree stumps and show any beast your weapon. He will drop over dead.....From laughter !!!
LMAO PS- That's a joke. literally.

I'd second that advice. You might get hurt in this forum from the hundreds of knees jerking at the mere mention of (looks right and left carefully, the coast is clear so he whispers cautiously) "45-70".

Hi!

I rebarrel my Ruger no 1 from 243 Win to something in caliber 45. But it�s difficult to choose between 45-70 and 45-100 right now. I allready have a 458 WM and 458 Lott in caliber 45 in bolt rifles and also one .500 NE on a Ruger no 1.

I like to reach +2100 fps with 400 grains bullets and 2200 fps with 350 grains bullet in this rifle and I think 45-70 is good for that when I�m looking at load data from Accurate powder for the caliber 450 Marlin and 45-70.

I�m fraid about the case life if I load 45-70 that high, but I don�t know, maybe there is no problem with that at all.

Now, I wonder if anyone here would like to help me to choose on this two calibers, and maybe answer my question about the case life. I would be greatful if anyone had load data for the caliber 45-70 too.

Best regards
