I know this has been discussed before but for some reason I can't get the search window to stay open. I have a Lefaucheux revolver about an 1850. I want to reload some pin fire ammo for it. It has been checked by a reliable gunsmith and given the ok. I want to make sure I have the correct caliber before I order the expensive components. The six cylinder bores measure .33" in the rear and .30 in the front, the muzzle also measures .30. Is this what is referee to as their 7mm or.32 caliber? Does anyone have a suggeston for componants?
