[QUOTE="kai, post: 1552010, member: 98994"] Roughwater, Thanks for providing your test results with 8133 powder. I'm shooting the Hammer Hunter 143 gn bullets and new Nosler brass loaded to a similar COAL of 3.495 from my Proof Carbon, 26 inch barrel with 8 twist and CCI 250 (magnum) primers. The bullet was seated with .020 jump to the lands. Initial MV from my new barrel with 88 gn. of N570 was 3,559 fps but after 90 rounds through the barrel, the same load is producing around 3,615 fps with a [U]very[/U] slight hint of bolt lift on my Nucleus action. How many rounds do you have through your barrel? Perhaps it will speed up. What pressure signs are you seeing? [/QUOTE]
