Many years ago my cousin and I loaded 150 gr Centrex??? flat point over 30 gr of 3031. I have loaded Hornady also in 170 gr and Rem 170 gr hollow points again with 3031. I stay a bit below max and have not had any problems with my loads and have killed a bunch of deer with them.
I also push the Hornady 170 Gr, with 3031, It’s been a great load for the 336. If looking for a little more range the new Flex-tip bullets and lever-revolution powder will give you a much flatter-shooting bullet.
