One of the guns I brought to shoot was this years BAG day acquisition, a S&W 629 in .44 magnum. I figured the large diameter bullets making the effective target size a little larger would compensate for the magnum recoil. Turns out not so much.
20 rounds down range, 15 hit the hit the 8.5x11" sheet of paper and exactly one clipped a target circle.
In my defense, this was shot at 11 yards (minimum distance the club allows), and this gun is the newest addition to the SandCastle weapons locker. Even after the 20 rounds for the target, I have less than 50 rounds through it.
Still, this is why the class exists. Sorry to set the bar so low ;-)
