My 8.5 twist shoots the 139 Lapua's very nicely.

AJJ should have an answer to this, he is generally up to pace in the big boy game. What say ye old timer. LOL

I shoot an 8 twist 3 groove Lilja. I shoot Sierra 120s for Chicken and Pigs and 142s for Turkeys and Rams.

As soon as I run out of 120s I am going to start using Sierra 123s.

The (OK, maybe just mine) 8 twist does just fine with all 6.5 bullet weights. It even shoots the 107s into nice little .75 MOA groups out to 300 yards.

I am coming up on rebarrel time and will be ordering another Lilja 3 groove. In fact I have yet to use another barrel brand for my past 6 or 7 barrels.

I've shot four different 8 twist 6.5's without any problems with the 107's and 108's. Seems at least possible that there are some heavy 6.5 bullet designs that would prefer 8 twist to 9. That said, Dave Imas has forgotten more about this game than I'll ever know.
And be careful with that "old timer" stuff, you insolent pup.
