I am looking for a good 30-30 load suggestion. I have some 170g RN Fp. Wondering what powder I should use and how much?

I use 33.5 gr. of W748 with the Speer 170. It's not the only answer, but it works.

A mild load that always shoots well for me is 31 gr IMR-4064 behind the Hornady 170 gr FN.

Sounds like you may be shooting cast. I've found that 35 grains of H-414 with the RCBS 30-180 FP is the most accurate in 4 thirty thirtys I've shot. That load also shot good when using a 173 grain FP.

Yep, 748 is your huckleberry, good velocity, lower pressure, longer brass life.

As Youper and Sam have said, 748 and 4064 have been go-to powders for the 30/30 for years. I might add 3031 is a good one for this cartridge. I used to reload a good quite a few rounds for my old Marlin 336 when I was a kid. I haven't loaded much for the 30/30 in many years but if I were to start experimenting for it again I would grab a jug of LeverRevolution. The Hornady manual makes it look tempting.

Leverevolution with 150 and 170 gr bullets max doses right out of the Hodgon manual...mb

30grs of 3031 is excellent in my 30-30’s using 170’s.

30 grains 3031 just like Bearcat said

That is the classic load for the .30-30. There are a lot of combinations that work great in the .30-30 and load data is easy to find.

Thank you for the reply's I will try the 748 and 4064 since I have some of both. Let you know I'm going to the range tomorrow.
