These were from a few years back. Not sure when PRO Shells first came on to market, but these are among the Good one's!!! They hit hard, had a great Spread, and the Colors were Good. Awesome Shell's, BIG had a Good One for a while!!! To bad they didn't stay this way. Big thanks to Break Charge for hanging on to these as I'd never had PRO Shells before. I can't remember exactly, but I think I heard these were no longer in production, I could be wrong. If they are still being made, I may need to grab a case.
