Nope I've never shot one, in fact I've not even seen one in use when I was on the range around here. The guy who I buy all my guns from shoots one tho, I'm sure I could try his if I ever found myself on the range with him but then he shoots at different ranges than I do. I've just given up on the 12 for now. I'll stick with the 28 as my primary gun and the 20 and .410 for a change up from time to time. In the morning when I go I'm taking my 28 and .410 both.
