I have very good groups using green tip IMI 69 grain .223 and the BRI sabot 12 gauge slugs , 1 oz. The scope base is on the barrel so play in the action is moot. .22 CCI mini-mags are the most accurate but have chosen the 40 grain solid remington rounds for solid hits on small game that won't damage meat as much as a stinger or other hollowpoint may.....<br><br><br>I think the key point is that this is a survival weapon I use for food gathering versus self defense other than dangerous game. <br><br> I have made one inch groups from a bench using a 6-18X tasco scope that does double duty as a spotting scope, binoc's etc etc. On the scope I use a rubber band cut from an auto inner tube versus a set of scope covers to protect the optics as the rubber can be used for a sling spear etc if needed.<br><br><br>The rig is stored in my vehicle kit disassembled in a bag I made from an old filson tin cloth jacket. <br><br>Hope this helps with some ideas..........<br><br>Stay Safe !
