260 Remington powder compression
Trying to run the new 140 ballistic tips. I have tried 7828ssc, H1000 and H4831SC. All seem to be quite compressed when approaching max loads to the point that the bullets are seating inconsistently for depth. Next up will be H4350, IMR4350, RL17 and maybe RL19. Looking for something that is temp insensitive for the heavier bullets in 260 Remington. What other powders for max performance with 140 ballistic tip and 260 Remington?
