[QUOTE="Jimm, post: 79529, member: 9"] Hey Daniel, I'm shooting a .243 AI with 7.5 twist bbl.. Recent ladder tests with h4350 powder and 107 smks resulted in the top end of the ladder ( 42.5 grs. of H4350 ) giving 3150ish velocities and promising accuracy. Further tests are in the works.Please note that I never reached any pressure problems so perhaps velocities higher than what I achieved are possible with accuracy However if accuracy is your top priority , ther eis another load of H4350 under 107smks that gave me one hole groups at 100 and 1"groups at 300. Velocity is not high but depends on what you want . The load was 38 grs. of H4350 under 107smks, seated touching the rifling. Hope this helps , am presently working on other combinations .
