I need some advice with what is happening with my 357 Mag loads. I use a 158 gr RNFP (Badman) and CFN (Penn) for my reloads. The OAL on these rounds is 1.590". My final inspection of the completed round includes a check with a gauge.They feed and chamber fine in my Winchester 73 and my Vaqueros. I was shooting with a friend last week who had his Henry Big Boy 357 with him. My rounds would feed from the mag into the breech with out a problem,but not all the way in. About .125" of the case was protruding. I asked if he had been using 38 specials in the rifle and the reply was yes. I thought it was crud build-up from the shorter round. I spoke to him later and said he had throughly cleaned the chamber and now a factory 357 round (AE) would chamber,which it wouldn't before,but not my reload.........Chamber length?
