I shoot a lot of the 4350s and a fair amount of R-19. Melvin Forbes of NULA likes 4350, and so do I. My best load is with the 140 Nosler Balistic Tip behind IMR4350.

I have yet to try ANY R-17 in my rifles. That will probably be a good summer project for me.....

I was hoarding when hoarding wasn't cool.
