Had a first for me today...one of my handloads caused a failure of a Starline case in my G20. It blew out the magazine and broke the trigger and slide stop and bruised my trigger finger. Something hit my cheek near my nose and drew blood....not much but if it had hit my eye it would have been a problem.
The load was 6.0 gr Universal under a 180 gr jacketed Remington. According to Hodgdon, 6.4 gr is max.
I double checked my powder measure and pulled about 15 bullets and weighed the charge and all were 6.0 gr. I'm not blaming Starline, but it is pretty **** hard to get 12 grains of Universal in a 10mm case so I don't have an explanation for what happened. I fired about 20 rounds of the same batch of reloads in my G21 with a BarSto 10mm conversion barrel with no incident.
A few months ago we had a Remington bulk 22 LR blow the top off the slide on a Walther P22 with a suppressor. Case failed right in front of the rim. Remington said their ammo is not designed for use with a suppressor and Walther said it is Remington's fault....gun is now an example of poor quality or workmanship....either Remington's or Walther's.
Bottom line, wear safety glasses when you shoot anything....they will save your eyes!!
