Modern fluid steel chamber blow-out



Shell remains



And Gracias a Dios I've got a Smith barrel on the way for evaluation also!! Please look in the back of your safes - gotta be a blown up JABC Twist barrel to donate to science smile

In addition to the blow-up analysis, my real hope is to find a non-destructive method to evaluate barrel integrity.
