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