Chuck thanks for the tips, you don't even want to know what I did to my basement wall yesterday when I cycled a round through the action to see if it ejected OK. Luckily the 25-20 does not have enough power to go through a coffee can of brass, sheet rock, foam insulation and a block wall, the wall survived. It is a little touchy, I don't know why they put that sliding button on the side, see no function for it.
