[QUOTE="DANTEC, post: 53658, member: 685"] no really need a 1 in 10 for 300 ULTRA , 1 in 11 or perhaps a 1 in 12 can works better it s seem that 3 groove have better life time than regular 6 grooves , I prefer use 5 grooves barrel because bullet deformation is asymetric , 5R grooves are very good for barrel life ( barrel wear by square of the groove smashing ) but seem the same for throat erosion Why you not try G Schneider polygonal barrel ? regular 300 ULTRA is a bit broad for target shooting / long range , a thighter throat will be nice and a tighter chamber base good shooting DAN TEC [/QUOTE]
