I work for a gunsmith (friend of mine) part time. I have an old Stevens single shot, bolt action 22LR that has chamber erosion from the previous owner shooting shorts in it exclusively. I have had the barrel tested for pressure and found it will contain the pressure from a 22WMR. Does anyone have a chamber reamer in 22WMR that i could borrow/rent? To purchase one for the shop is cost prohibitive, since it is a rarely used piece of tooling. The reamer would be used one time by a trained and experienced gunsmith only. any options or interest is appreciated.
