I've only been able to do a bowling pin shoot once, but it was awesome! I went at it with my STI Edge and I did fairly well. I lost to a guy who was using a .22. He was a regular competitor so I don't feel too bad. One thing about .22, you better hit it in the center. If it falls on the table, you're done. The STI Edge is an incredible soft shooting gun and it soaks up a lot of the .40's recoil. The .40 really smacks the pins and can easily knock them off the table even if they tip over. The fiber optic front sight makes it very easy to aim.
The ATF should be a convenience store instead of a government agency!
