[QUOTE="tstarky, post: 730359, member: 54641"] [b]Re: Ladder test ???- now sub MOA shooters[/b] Eureka! After finding the best bullet and powder combos and then performing a 5 group jump test (incrementing jump .030 each step, ranging from .010 to .130) we have a pair of sub MOA, @100 yards, rifles now. :) These are factory barreled rifles. The Remington 700 7MM RM loves the Berger 168 VLD hunter with 65gr of RE22. The bullet jump is .010. The Remington 700 30-06 is happy with Sierra Spitzer's 180gr and 58.3 grains of H4831SC powder. The bullet jump is .130. I will be performing a finer jump test of .002 increments, ranging .040 (+-.020 sans jamb) over the next few weeks with hopes of shrinking the consistant sub MOA groups. Also noteworthy is that we added an adjustable Muzzle break to the 30-06. The group size shrank about 40%! Got it from Brownels [URL="http://www.brownells.com/rifle-parts/barrel-parts/muzzle-brakes/adjustable-muzzle-brake-blue-660--sku100-000-413-1540-5819.aspx"]Blue, .660" : ADJUSTABLE MUZZLE BRAKE | Brownells[/URL] We did not have time to optimize the adjustment setting but will be performing that fine tuning after the completion of the jump test.
