[QUOTE="Hugnot, post: 2907343, member: 115658"] I like the Barnes Match Burner bullets - I buy 105 6mm's, 120 & 140 6.5's My 6mm barrels are 8 twist so I have not used the 112 grain Barnes Match Burners, a long pointy bullet. I did have a 26", 8 twist, .243 diameter, 6mm-06 barrel & got velocities of 3150 fps average with 105's & 107's. Pressure appeared to be normal with moderately flattened primers having traces of cratering. I was able to blow up 87 grain VMax bullets - gray smoke, no hits at 100. If Barnes provided G7 BC data I could determine Match Burner form factors. [ATTACH]495305[/ATTACH] I think a 7.5 twist is needed for the long & pointy 112 grain Barnes Match Burner & cartridges smaller than 6mm-06 would not produce enough spinning/centrifugal force to destroy the bullets. The OAL of my Barnes 105 grain Match Burner Bullets varies some 2-3 thou inches. I used an average of 1.198 inches. [/QUOTE]
