I am in agreement with fireball.

The FTX series bullets, Lever evolution powder, CCI 250 primers, with matched brass is my favorites for better velocity out of shorter barrels.

I believe heavier bullets will present better Terminal ballistics. But no science there just belief and bias.

I usually end up settling on the lower range of the powder chart. In the 30 30, very few will tolerate " max " load for me.
