Ok, lets give this a try. I have a pre G2 contenderand a new custom shop 357 maximum barrel. I went to the range tonight and heres what happened. First 2 rounds had a light primer strike, 3 and 4 blew the action open. No as far as a overloaded round, this wasnt the case. I measure ever round when I loaded, and when I came home tonight, I took them apart and measured again. These loads came directly from the Contender load book and were not listed max. Whats going on?
