I just got a Deviant Hunter action, and would like to use it for a 6mm build that would be used for hunting Coyotes and possibly Antelope. I currently reload for 6BR (for 600 yd. competition) and would like to stick with a 6mm for this build. I've read quite a bit hear about the 6BRA and am interested in giving it a try. I'm thinking of useing the Sierras SPT 85gr for the Coyotes (hopefully they won't be too hard on the pelts), and preferably 105's for the Antelope. I currently use a 1:7.5 twist and am confident this would work nicely for the heavier bullets, but would it also work well for the lighter ones? Thanks.
