[QUOTE="Barrelnut, post: 1105885, member: 74902"] IMO work on the brass first. Remington brass can vary in weigh quite a bit. 1) Sort the brass to +/- 1 gn. 2) Neck tension is important. Make sure the brass you are using all have the same amount of rounds fired. Like a 3 shots fired or all 2 shot fired. 3) Trim the necks to same length each time. 4)Debur the flash holes. Shoot and see if there is improvement. 5) Anneal the brass. Prep and shoot again. I think you will see some improvement by all this. 6) If improvement is still necessary. Weight sort the bullets into +/- 1 gn. groups. Take each of those groups and sort by bearing length. A-Max bullets are good but they do vary in weight and bearing length more than say Bergers. And that is ok. A-Max bullets can shoot very well at long range. They just need a little more care in the sorting. 7) Still got problems? Look at the consistency of the powder charges and consider trying another primer. The Federal primers are very good however. Other thoughts: -Don't start speed test with a clean barrel. Get about 6-10 rounds thru the barrel after cleaning. Then start the speed test. It takes the barrel a few shots to settle down after cleaning. -Don't let your rounds set in the hot chamber very long. Try to fire with 10 seconds or so of loading the chamber. - Keep the powder somewhat level in the cartridge when you chamber the round. As in, don't have all the powder at the front of the cartridge on one shot and all of it at the back on the next shot. Load single round, don't shoot from the mag during testing. [/QUOTE]
