I've got an 1895 guide gun that I enjoy shooting immensely. I've recently put a leupold fixed 2x scout scope on it and zeroed (or so I thought) to 50 yards. I have the following 3 loads I'm shooting:
405 grain cast lead with 12 grains unique. 1.5" groups of 10 rounds @50 yards is very easy to do and, of course, very little recoil.
340 grain cast lead with 12 grains unique. Same groups.
I've also loaded up a hornady 300gr soft point bullet (#4500) in 42 and 43gr of H4198. This is a pretty stout load - very close to federal game shok.
I've always been under the impression that significant changes in velocity would not affect left/right down range -- only height of impact due to velocity and bullet drop over distance. That doesn't seem to be the case with my 1895. With my 300gr hornady load, the zero moves to the right about 4" on a 50 yard target. I thought I might be "flinching" right, but I shot a couple dozen to be sure and it's definitely right of impact of the cowboy loads.
Does this sound normal?
