Twist Recommendations with 6BR or BRX and 60-69gr Bullets

[muddy72]

I need some twist info from those who shoot the 6BR or BRX with any bullets in the 60's. Is there that much difference between a 13 and 13.5? What your success story?

Thanks

I shoot Sierra 70 grain match king bullets in a 13.5 twist 6BR with excellent accuracy. My last 5 groups had four in the mid .2s and one in the .3s, and this is with about 1,500 rounds down the barrel.

I shoot 14 twist barrels in 6PPC and 6BR for the weight of bullets you describe. Berger Column bullets and LT-32 powder gives me .150 groups in the 6BR. 13.5 twist would be OK, but 13 is too fast.
Good shooting,
Bill
