It will shoot just fine..may not work as well as intended but it will shoot just fine. Pellets per oz (28 g) is how its measured for powder. you will just have a gross amount of weakness in your shot. Your now shooting x size buck shot through whats set up to shoot birt shot. I think that should be correct, I havnt started reloading yet but I have read about it. all in all you can shoot it just fine depending on the set up of your shotgun I dont understand why you dont just go up in the bush and shoot it off. The only time I ever go to the range is when im sighting in a gun, or im shooting a wepaon not legal in the bush of canada.
for david theres alot of reasons. at my rod n gun we have a 100 yard outsdie rang and a 50 yard in door. I dont understand how my club is so nice, we live in the middle of the bush but I love it. ANYWHO we arent allowed to shoot shotguns in general anymore cause the stands we pin our targets on are gettin blown to shreds to quickly. also when ever I end up goin to the club I seem to be the only memeber there most the time. Occasionally I bump in to some one else but we just have soo many things at our club that its almost desolate. we have an archery range set up with 3d targets takes rougly 2 hrs to get through, shotgun skeet range, old western town range for competition, 2x shooting ranges indoor and out, and a camp ground with a numerous boat launching areas.
