75 gr bullets through a 1-8 twist

[Lefty Trigger]

Will this work ok in a 6BR Norma? I'm thinking the twist rate is too fast for a 75gr. If so anybody got any good starting loads for it using Hornady A-max.

Be fine. Just don’t try to reach Mach 2 with ‘em, or even close. 3,000 - 3,100 fps be fine.

I shoot Sierra 70 HPBT with 29.3 gr. of N135 about 3123 avg. Does great at 300 yards. 1-8 twist, 32 inch barrel.

Thanks, I'm actually seeking a great load just for 300 yds.

I've shot literally thousands of 70 & 75-grain bullets out of 8-twist barrels chambered in 243-Ackley's and 6-Dasher's, at velocities between 3500 to 3800-fps. Using fast twist barrels on Prairie-dogs gives a whole new meaning to "air-time, flips, and carnage" !.!.!

Have run many 55's at 4000 in 8 twist, never a blow up.

I have run many 87 V-max through an 8 twist 6BR . Gun averaged .288 for 4 , 5 shot groups. Nothing wrong with that. You should be just fine.

Well I have tried several reloadings with the 75's and the barrel just don't seem to like them at any speed. It will shoot about 5/8 inch at 300yds with 107's so I think i'll just stick with them.
