[QUOTE="dkhunt14, post: 999694, member: 14053"] Mike tighter fitting brass always shoots bigger at 1000 yards with the same loads Bullets and everything the same. This with every gun we tried it in. It seems to throw vertical fliers out of the group and they almost always go up. Sometimes really far up. We have guys that test almost ever day during the summer and they all say the same thing. If you look back at the shortrange benchrest guys. When they went from fitted cases to full length sized cases they immediately starting breaking records and shooting smaller aggs. The aggs tell the story because anybody at any time can shoot a lucky target or two. The aggs dropped a lot and as more did it the field tightened up a lot more. When that smaller reamer is used you have to compensate with the die. Guys say you can't move the base but they are wrong. We even have guys that made tools to tighten up primer pockets. The one guy made a die for the punch press and hit them with about 40,000 pounds of pressure. It tightens them up. His brother which was a tool and die man made a split block tightened by two screws with a plug the size of a primer. You put the plug in the primer pocket and tighten the screws, then you loosen and turn 90 degrees and do it again. Primer pockets now are as tight as new and the bases are back to new. Matt [/QUOTE]
