[QUOTE="tim_w, post: 1818581, member: 11132"] Its ok after this thread I'm not even sure what I mean anymore.😵 Seriously what I am advocating for LR hunting is sizing a case only the absolute minimum needed to reliabily chamber and extract from your chamber in the conditions you hunt in. For most that means a chamber die setup that gives you not more than 0.002 body clearance and 0.001 in headspace. Why? Even if we assume a case could have 0.010 case body clearance and shoot the same tiny groups? Case life. Min clearance also does not hurt accuracy I'm fairly sure no one is arguing that point I hope. Sorry if how I stated things made it confusing. A large part of this thread seems to be going in circles IMO. IMO fl sizing done correctly allows for looser tolerances between things (chamber runout square bolt face, case runout etc) being deadnuts perfect with only the smallest degree in accuracy/consistency possible loss which I can only see coming up in BR comps. Most people on here are not concerned with 0.100 moa 5 shot variances. But it does seem the majority want to use the highest accuracy node possible without case pressure signs abd getting the most reloads from their cases. IMO best way to do that is hold sizing sized clearance as close to chamber as allows reliable in the field chambering. [/QUOTE]
