.050" Bullet Jump
I've used between .030 & .050 with the Barnes TSX & had good accuracy and velocity. I did some with .010 & backed off the charge weight & increased slowly and actually surpassed max load in my manual by 2.5 gr with H4831 before seeing pressure signs and it was flattened primers so nothing really bad like hard bolt lift. However, I got better groups when seating at .050 like Barnes suggest than I did at other COAL whether closer/farther from the lands in my 280 Rem. I did break 3K fps over my Chrony with the load using both H4831SC & RL19. Hope this helps.
