.375” North Fork SS & PP

[PHOENIX PHIL]

I finally have access to North Fork bullets (per Kevin Robertson' suggestion).
Since the 300 grain SP is a pure copper, pure lead, bonded bullet I'm thinking of using the Swift A-Frame loading manual as the starting point since the two bullets are sorta, kinda, similar.

Anyone have a better resource idea for starting load data? (.375 H&H)
Thanks

I use IMR4350 behind the 300gr pills, both NF and A-Frame. Start at 72gr and work your way up. My most accurate NF load is a couple grains less than the most accurate A-Frame load.

Good info. Thanks.
My most accurate & consistent A-Frame load using H4350 produces single digit SDs.

Well, there you go, and RE-17 to boot!
Awesome! Thanks!
