I am looking at buying a new tikka 30-06 with 1:11 twist rate and am trying to figure out weather I will be able to use 220grain bullets. I go hunting in remote areas that have a lot of grizzly bears and feel more comfortable with a 220g for bear defence. That can be the seconds part of the question also weather I'm better off using the highest grain possible for bear defence but mainly would like to know if the 220 grains will do ok in a 1:11 twist 30-06
