Have burned quite a few rounds shooting clay and doves. My experience is a Vinci will run fine fresh out of the box. For my use so far, it is an upgrade from the SBEII, I traded in for the Vinci. It is lighter, swings smooth, and even new, cycles better with less cleaning and lube then my SBEII did. It comes at a slight cost of a little more recoil. I very seldom goose hunt and only get a couple of turkey tags each year, so most of my loads will be very manageable. Shot a buddies hot load 3" shell he claimed it was 1700 ft. per second round, OK once, I don't know about all day in a blind though.
