[QUOTE="VinceMule, post: 3056539, member: 122164"] OP, would be much better to have a new barrel installed on the Ruger #1 instead of a re-chamber. As the throat dia wears, the gunsmith has to fit the reamer pilot to whatever the larger size has become. Some gunsmiths have a large inventory of reamer pilots Per caliber and some do not. If the reamer pilot is too small for the worn Throat dia, the reamer will just bounce around, creating a helter-skelter chamber. Also, there is no telling how crooked the existing chamber is about the bore axis. AI chambers are shorter than the parent cartridge by at least .004. You could cheat, but you may have some case stretch. You can expand the necks up to 7mm, then neck down creating a false shoulder to headspace on. Keep in mind your goal regarding the accuracy requirement of the new chamber. [/QUOTE]
