This Saturday starts our rifle deer season here in Missouri. And I just got a scope mounted on my Browning 1885 in 45-70. I am shooting 300 grain gas checked flat nosed cast projectiles from an RCBS mold over 45.0 grains of IMR-4198, and have it sighted in with this new Leopold scope for 100 yards to hit right-on. But I didn't shoot it for any other distances and won't be able to before that critical day. Does anybody know about where this load will hit at maybe 100 feet and 200 feet from the muzzle? I don't know how to calculate trajectories and usually just shoot them at different distances. But this time I didn't get a chance.
