[QUOTE="Alibiiv, post: 1576829, member: 69192"] I wrote that the OP was limited to his choices because he had a "magnum" rifle/calilber. He was talking about how he loved the 30-06. When I read that he had a 7mm RemMag due to the fact that his bolt face was for a magnum cartridge, 7mm RemMag, he was limited to what he could build, "unless" he wanted to change bolts. Your .270WSM and .300WSM have a base diameter of .535 each, the 7mm RemMag has a base diameter of .532, thus the cartridges and bolt face are compatible, and yes means that the OP "could" build a .270 WSM or .300WSM on his action. However he could not build a 30-06 Government because the base diameter of the 30-06 is .483 thousandths of an inch; [U][I].052 thousandths of an inch smalle[/I][/U]r. With that it makes the bolt face too large, the extractor will not grab the base of the cartridge properly nor will it support the base of the case. Yes you "can" build, and oftentimes is recommended, a short cartridge on a long-action cartridge, "as" long as the bolt faces are compatible, or can be opened to accommodate the new rechambering. In this particular incidence, for me, the bolt face controlled what the OP could build on his 7mm RemMag action. [/QUOTE]
