I was cruising Kriegers site and see they have a couple 6mm .237 15 twist 6 groove bbls in stock,,I am in planning stages of a 6BR .268 neck zero freebore to shoot the 60 Sierra and similar light weight bullets mainly at 100 yards but 200 and 300 some also,,
are there any advantages to a 6 groove over the 4 grooves ?? I think they use to be more widely used than they are now but I have no experience with a 6 groove bbl ,,
