Can we assume that you are running a single shot? I have had the best accuracy personally from a good quality 4 groove. Shoot straight bud.Want to put a 22 ppc barrel on my savage for 100 yd ubr. Im going to do 13.5 twist but should i go 3 or 6 groove? Profile? 0 freebore?
Number of grooves is less important than TYPE of lands. Polygon or "Ratchet" style will give you a better gas seal and less friction, both of which add up to higher velocity. Also, the smoother land edges cause less bullet deformation.Want to put a 22 ppc barrel on my savage for 100 yd ubr. Im going to do 13.5 twist but should i go 3 or 6 groove? Profile? 0 freebore?
Sea,I have a PTG bolt face ordered. @boltfluter it is a 110E action but will be used single shot as it is now. I think the Kreiger is offered in 3 and 6 groove. Not sure of profile either
You need at least twoThere has never been any proof that the number of grooves matter.
