Since you already have a couple of 45 cal rifles, have you considered something like the 400 H&H, 450/400, 500/416, 416 Rigby, 411 KDF, etc...? They will all get a 400 grain bullet moving at or better than 2100 fps, and you'll have a new caliber to play with instead of the same old 45's.

I find with my Ruger #1 in 45-70 any time I get above 1800 fps that case life is severely reduced. Though you have to understand my #1 only has the 22 inch barrel. With a rebarreled longer barrel version you could coax alot more fps out of it with the same pressures I am seeing.>John

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.
