Wow, that's reaching back...I used to shoot one long time ago. I had a CVA Big-Bore Mountain Rifle for a couple years and like a fool I sold it.
For paper punching, I used 75 grains of ffg...Inside of 60 to 65yrds...it was a good load. I'd have to adjust my point of aim, because this gun was a hunting gun and so sighted with my hunting loads in mind. If a shoot had targets out at 100 yrds plus a little bit, I just used my RB elk load due to the drop of the projectile. Much beyond 50 yrds...it dropped pretty good, with just a 75 grain load...
For hunting elk, I used 105 grains of ffg, under a patched RB, and it was a hammer on elk.
Using a Maxi-Ball I used 95 grains of ffg, stout load to shoot from the bench, but great elk medicine.
