Looks like someone can't handle a challenge.
All the challenge of stock class pump play but with out the, you know, pumping. I've had a blast on the airball field with nothing but a T8 and a pocket full of mags.
However, while .50 cal would be better than .43 for pistols, I'd rather stick to the easier breaking .68 cal. It's hard enough to get a good hit with such a self imposed handicap, having a ball that's inherently more likely to bounce will just get frustrating.
