Very nice! What twist rate is your barrel? I've done most of my 45-70 shooting with my Pedersoli 1874 using 405gr lead bullets but I plan to do some experimenting with heavier projectiles this spring.
1 in 18 twist. I’ve got 400 or so rounds down range. I’m going to up the charge though a bit as find my load gives me the occasional low velocity. I’m thinking of going as high as 1250 as it get punishing on the shoulder above that. I’ve actually found the campro as accurate as my 535 postnell. I know, blasphemy.
