I'm about to have a 6br built & thought i'd choose a Kreiger barrel. i just saw a print out of their barrels & see that their 6 groove is only available in twists of 1;13, 14, or 15. the 70 to 95 gr bullets i want to shoot seem to call for a 1;10 or 1;9 twist. kreiger makes a 4 (four) groove for 243/6mm in 1;8, 1;9, 1;10 etc. will the 4 groove provide the accuracy most shooters require/expect, or do i have to look to another manufacture? thanks as always/ chaz

You can rest assured that Kreiger is not going to make a barrel that is not match-grade accurate. 4-groove is probably the most popular especially in the fast twists. There's a tremendous centrifigal force on the bullet jacket and the fewer cuts in the jacket from the rifleing the less chance of ruptures. Don't hesitate to discuss your project with the good folks at Kreiger. They are both barrel makers and shooters and will not steer you wrong.

IMHO a 9 twist will give you a much wider range of bullet choices and will not give up any accuracy over a 10T.

Krieger's are topnotch, but you can also consider PacNor. Excellent service and quality.

And if you have not perused 6mmBR.com, it's loaded with info.

Check out Lilja barrels comments on 3 groove barrels. They are doing well in bench rest with 20% longer barrel life. I would feel confident with a 4 groove. Krieger has a tremendous reputation.

By the way, I believe Dakota Arms uses Lilja barrels as standard.

gents/ thanks/ordered a 1;9 4 groove from kreiger

Buy a 1-8 twist and you can shoot from 107 grains down to 50 grains without trouble!
