When I fired the Speer/CCI shotshells out of my Taurus 85SSUL, I was only able to get two fired before the gun locked up. The recoil caused the shot capsules to "pull" and block the rotation of the cylinder. This didn't happen in my S&W Model 13 or Model 681 because they didn't recoil as much. I wouldn't trust more than two shotshells in a light gun, and I've been able to hit snakes at reasonable ranges with bullets.
