[QUOTE="Boisedoc, post: 2604186, member: 99050"] I am having a smith build a 300 WSM. I plan to shoot 212 eldx bullets. He has a SAAMI reamer. I’ve done a lot of research and the consensus is a .200 -.220 freebore. The SAAMI spec is .188. He said I could load a dummy round for him and he can ream based on that OR I hear there are ways of ordering a reamer with the demensions I want though I only plan to build one rifle. Question I have is how to build a dummy round to approximate a .210-.220 freebore? I have a comparator and could build a round with the cartridge base to ogive dimensions based off of the calipers and comparator to approximate the freebore (I understand this isn’t very accurate). If I build the round with the Boattail at the neck/shoulder then it will be about a .280 freebore. Can I get some advice? [/QUOTE]
