PAScott.....Enjoy your new modern rifle. Chances are that you will be putting the Factory ammo in the same hole at 50 yards. If you read other Forums you will see that the .450 & 45-70 debate is a losing argument with some people and eventually you will get spit on. Just kidding! <img src="/ubbthreads/images/graemlins/smirk.gif" alt="" /> All I can comment on is the .450, I hunt with it in the Adirondacks and shoot the heck out of it during the off season. I can't pass judgment on the 45-70 because I don't own one....Yet!
