[QUOTE="Iron Worker, post: 972756, member: 2332"] Ok AZ knows I'm experimenting with Re#25 in 6x284. Happy his bbl has a 1,000 rnds down it and its still a shooter. I was burning 51.5 of Re#22 in 30" Brux bbl 8" twist Hornady 105 BTHP produced an average MV 3350 with poor accuracy and pressure signs. . This time I switched to Re#25 and Berger 105 Hybrids seated out to touching lands. Fired 4 shot groups starting at 51.5 -53.0 1st group(51.5) shot well under 3/4MOA at a 100 and average MV of3375 Zero pressure signs 2nd group(52.0) shot a 1/4 MOA !!!!!! and average 3400 I was very happy. Zero pressure signs 3rd group (52.5) group opened up to 3/4 MOA and average velocity 3440 and slight flattening and cratering of primer. 4th group ( 53.0) produced an average MV of 3485 ranging from 3470-3525 but group was under 1/2 MOA . But had shinning Ejector marks which means stop and reduce load. . So I'm back in the thumbs up camp for 6x284 . My new load will be 52grs of Re#25 [/QUOTE]
