[QUOTE="cohunt, post: 1702007, member: 94491"] yea, we have spoke about the min barrel wall thickness before-- this seems like its a preference thing depending on who you have thread the barrel or the barrel manufacture--I know it has been proven that too thin of a barrel wall does in fact cause muzzle swelling, but how much does it actually affect accuracy? Kimber threads their 300wsm and wm mountain ascent barrels with 7/16" threads, also many well known "recommended" gun smiths that build custom rifles will thread 30 cal pencil barrels in 7/16" also--- I agree with you that thicker is better and its better to err on the side of caution than go too thin, but I have seen 1/2 moa 30 cal rifles threaded 7/16 before and I have never seen about any safety issues so I guess if it comes to bench rest rifles then go for the thicker barrel wall, but for some lightweight hunting rifles it can work just fine to have thinner walls.
