I finished 2nd overall at the 1993 Second Chance pin match using a 7-shot Baumannize S&W 27 with the stock 8-3/8" skinny barrel, and 230-grain cast bullets (the ones we called "Lincoln Logs"). I bought the gun from Brian Enos, as a matter of fact. That year Jerry Miculek was right behind me in 3rd place using nearly identical equipment. We actually had an identical aggregate time, and I got lucky and beat him on the tie-breaker.

It goes to show you don't need anything real fancy to shoot pins, but load selection is very important. Those 230-grain .357 were the absolute best for shooting bowling pins. I'm pretty sure H&G discontinued the mold, and I think the only company still selling the bullets is GAT Bullets out of Louisiana.
