[QUOTE="Pdvdh, post: 1082660, member: 4191"] Your reamer will work. I think it has looser dimensions than ideal for a guy that's going to run an Improved version of any cartridge, because if you're going with an Improved version it infers to me you're looking to refine and maximize cartridge performance and accuracy. I don't design and manufacture chamber reamers, but I've learned that the folks that try to improve upon factory chambers would reduce the "LEAD" diameter to 0.0005" over bullet diameter. Not trying to be a jerk. I thought you were seeking advice prior to ordering your reamer. Perhaps your reamer supplier will exchange your's for a slightly different spec'd reamer. Or maybe you're happy with your current reamer. About 6 months ago I researched reamer deigns for an Improved .338 Lapua fairly extensively. Below is the reamer I specified and ordered. Doesn't mean it's the world's best ever .338 Lapua Improved reamer design. But it does duplicate many of the reamer features and specifications I found other gunsmiths ordering.
