[QUOTE="Mysticplayer, post: 156346, member: 8947"] BH, a great read and covers so many great points. I use the modified ladder method - 2 rds in small powder increases shot at 200yds. I watch for the groups to shrink then expand while keeping an eye on pressure signs/chronie. Narrows things in a big hurry and I can usually diagnose a rifle/bullet/powder in about 30rds. At least good enough to know if more shooting is worth it. A few points I might add: I always do my testing with fireformed or brass sized as I would always use it. I find there is a significant range of error using brass out of any bag/box. Neck turning s used just to take the high spots off the necks. Cleaned up 70 to 80% of circumferance. All brass is sized for min runout. A runout guage has helped my quality of ammo more then many widgets. I can now track what does or doesn't work. I consider 2 thou to be my working max. Seated ammo also has runout 2 to 3 thou - less is better. I use the Lee collet die and not found a better die for the job. I have used the reg seating die for Lee, RCBS with excellent results once I had the runout guage to diagnose where problems were. modifying the seating stem for long bullets is the biggest aid to getting BR quality ammo using reg. seating dies. Match primers work for me and I find the CCI BR family handles higher pressures yet is a 'softer' primer. Don't expect to get match accuracy with non match bullets. Many hunting bullets are not made to drop into the same hole. Some can't hold MOA in factory QC testing but are ok cause their intended use/user doesn't require bughole accuracy. I use Hodgdon powders almost exclusively. I find it works very well and they all burn best at the 'higher' node. Stock/rests, optics and trigger all affect ones ability to shoot small groups so that has be considered. Also, how the ammo is handled. Make sure that it doesn't get bumped too much or the bullets can get knocked out of alignment. Pretty common with low neck tension ammo. Jerry [/QUOTE]
