Since Oklahoma has finally passed the law that we can hunt with our suppressors I have to rethink my barrel options. Would a #4 contour @ 20" be stiff enough for a Tbac 30p-1 suppressor? If my calculations are correct it would be .730 at 20". I'm thinking that would provide enough shoulder but not sure on the stiffness of the heavy sporter contour + my suppressor. This rifle will be used for coyote and deer hunting, so it will only see few long shot strings for sighting in and whatnot.
