[QUOTE="jimbires, post: 1553078, member: 11011"] 1 . I like to start at min powder charge , and find my best seating depth . then I add powder to get to my best grouping or velocity goal . 2. a primer pocket swager removes the crimp on the brass case from a crimped in primer . usually found in military ammo . a primer pocket cleaner cleans out the carbon in the pocket after the ammo is fired . 3. faster twist is necessary to stabilize longer bullets . a fast twist barrel can spin a short bullet fast enough the bullet will come apart . I believe in using a twist fast enough to stabilize the bullet , or a tad faster . don't go nuts by using the fastest twist available unless you are using bullets that need that much twist . 4. I neck size only for 2 or 3 cycles . this allows the brass to get fully expanded . then I set up my full length sizing die to bump the shoulder back about .002 " - .003 " it's been proven in bench rest that neck sizing only is not the most accurate . 5. I think it's hard to beat Lapua brass [/QUOTE]
