really thick(sometimes bad)
I shot about 3 cases and never had a ball break in my model 98
Weaknesses:
sometimes they dont break on the target
high priced
Conclusion:
It shot pretty well in my model 98 stock barrel ( of course the stock barrel sucks). My friends also have 98's hardly broke any paint in it. However being really thicked shelled they sometimes dont explode on impact, but sure as hell will hurt your opponent. : )
