[QUOTE="ultraedge, post: 968003, member: 36257"] Seating depth can make a lot of difference. Start with your bullet about .005" off the lands and shoot several groups. Then move away from the lands about .040" and shoot a couple more groups. Move back .040" more and repeat. Fine tune both ways from your best test groups. Once your best seating depth is found, you can lengthen the magazine if you need to. Gary [/QUOTE]
