After doing a couple k rounds for my 9mm with no issues I decided to load up some .357 magnums for my S&W 686..
Speer #12 lists a charge of 6.0 to 6.8 gr of 231 w/ 158 gr jacketed bullets. I loaded some once fired cases up with 6.4 gr's of 231, wsp primers, and 158gr XTP's.
When fired they don't "feel" hot (although I know this is very subjective..)
The trouble I had was they are VERY diffucult to remove from the cylinder after firing. I only shot 2, neither showed any indication of the primer flattening.
I know that diffucult extraction is a sure sign of high pressure, I guess my question is why? I'm well within published loading data..? Thankfully I only loaded 18 rds, and I'm going to pull the remaining 16 as I don't dare shoot them.
Thanks for any insight..
