[QUOTE="AZShooter, post: 507597, member: 5219"] I understand your frustration. You have read that others are getting with their 6mm-284s and 107s at much faster velocities than your rifle. If you do a long search you will find quite a wide range of results. One load that kept popping up was Randy Derks world record 6 targets 7” @ 1000 YDS 54 grains of Reloader 22 - Federal 210m primer - Sierra 107 grain Match King bullet - 3425 fps. I have no idea on barrel length or twist. I did a ton of research before deciding on which twist/bullet etc. I decided I wanted to shoot a 115. After reading that many shooters had issues with the 115 Bergers coming apart the DTAC was THE bullet to try. Many recommended a 1 in 7.5 twist for 115s. So I got a Bartlein 5R with that faster twist. I tried every possible variable with Lapua brass. Several powders, seating depths, neck tensions etc. Nothing shot well enough. I shot over 600 rounds, using up the best of the barrel's potential learning. So...I switched to the 107 Sierra which showed accuracy right away. While I had heard of superior velocities with RL-22 I wanted a powder that was more consistent over a wide range of temperatures. I tried H1000 and Retumbo. 57 gr of Retumbo worked the best. Velocity is a sedate 3265 fps. I'll use up the rest of the barrel 's life with this combination. The next barrel will most likely use 284 win brass and I'll get a slower twist. I may even try RL-22 as well. I can PM you my rather lengthy file on every load I could find on the 6mm-284 via the net. Ross [/QUOTE]
