Well it depends on the caliber of the gun and the range. I have used my Hawkeb 54 cal to shoot skeet to do so with any range and with out leading the barrel you use a 28 gage power piston [make a measure that fills the power piston to just barely pelow the top I used 80gr of pistol pyrodex but you will have to pattern your gun with the size shot and loads you want to try as they will shoot different.Onlythe 54[ 28 gage] and I believe its the 79 [12 gage not sure] or if you happen to have a caliber that matched 16 gage. unless its a smooth bore you need to be able to use a shot gun plastic sleevedwad like a sabot toavoid leading. Hope this helps. Lee
