Thought I would get out the Marlin 30-30 to take a doe or two. I never killed a deer with a 30-30.
So I am looking for a good load for my Marlin 30-30 lever action with 150 RN Rem CLs

try 34.0grs of h-335 or rl-15 36.2grs they should work in yours just work up.Good Luck

28.0 grains of RL-7. 2160 fps out of my Marlin 336ADL with Winchester 150 PowerPoints. Very accurate.

I use IMR-3031, I think it was made for the 30/30 and 150 grain bullets. Mines pretty accurate as well, good luck with yours.
