C'mon..........you're not REALLY here for the airguns.............
Do as I do'd and install the ad blocker from Mozilla. No more nasty images although most of mine were popups of a girl's butt with some cheeks that looked about to pop-out.
And I really dont want to sound cheap, but is it free? Also on the matter at hand ,targets, has anyone ever tried modeling clay for quiet pellet traps? I used to wad up little balls of it to use as targets and the reaction is pretty cool with a lump about 2 inches in diameter. sometimes with a wad or hollow point they pop like mouse. It seems like it would work along the lines of duct seal. Again leaning towards the less expensive aspect being a carpenter.
