I've been critized many times over the years for this opion but if you understand ballistics it make sense, "the 150 gr. load for the 30-30 is a joke, it does not shoot enough flatter to make a difference at sensable range" the 170 flat nose damages tissue better than the 150 RN and it most often exits a deer, entrance holes don't bleed, exit holes do. Think of that next time yer following little tiny almost unseen drups of blood. The old gun writer dribble about using all the energy inside is pure BS, it makes tracking difficult.
Lyman makes a 170 flat nose for the 30-30 and RCBS makes a better 180. The famed Savage 303 was almost identical to the 30-30 with a 190 gr. bullet and it was always consider much better for larger game as Elk, Moose and Grizzly till better rounds got popular in the 20' and 30's.
Buy the mould that looks like a proper 30-30 bullet.
