[QUOTE="slygunner, post: 36585, member: 2899"] My buddy has a Rem. Model 7 in a 22-250 with a 1/9 twist barrel. We want to do some tinkering with heavier bullets, now he is shooting a 55gr Nosler and his groups are averaging about 1 inch. Some of the questions that we have are: is a heavier bullet going to work better for accuracy and which bullet, what powder would be best so that you get good load density and so that all the powder burns up before it reaches the end of a 20 inch barrel? He is having issues with pressure(hard bolt lift) with 36.5grs of H380, whats the relation between a fast twist and this excessive pressure? I was wondering if some of you AR guys could help out with these questions also because you guys are generally shooting short, fast twist barrels. Thanks and Happy Hunting, slygunner [ 10-22-2004: Message edited by: slygunner ] [/QUOTE]
