How much lower in pressure would the 45-120 be at the load weight (350gr)and velocity (2000fps)that I get out of my 45-70? I do not have load data for Varget with the 45-120. 28k in the 45-70 seems to be pretty low in the pressure world. Plus Starline does not offer nickel plated case in 45-120 as far as I know. Hey, I am as crazy as anyone. I am trying to find a suitable 410 SxS to convert to a double rifle in 22 Hornet! Thanks.
