H4350 for this guy....best velocity!!

For me as well but I want to give this new one a try as well. Currently, I am pushing the 120 NBT at 3150 fps out of my 23.5" pipe with a full case of H4350. The 130 AB's are flying at 2,950 fps and the 140 NPT at 2,940 fps, all cloverleaf groups.

Are you guys getting better velocity and accuracy with H4350 than RL19? I would think RL-19 would yield more velocity.

What are you trying to reload it with.?

Never loaded .260 but superformance powder was almost the same burn speed as h4831 or rl-19. If those work it will also

In the 30-06 with 165 grain bullets [in a 24" barrelled rifle] Superformance will deliver right around 3000 fps safely.

Have you tried Reloader 17? Just curious to see how it stacked up to H4350.

Sorry, when you said "best velocity", I thought you tested it against other powders, and I was wondering how it compared to H4350.
