Yeah, it does get expensive right quick. That gun will go through about 50 pounds per event. The unit will buy one case, the owner will buy one case.
I can somewhat muscle around a 3" rifle by myself. Move it 20 or 30 yards on hard level ground without too much struggle. This one, my GAWD! I put the trail spike in the pointing rings, and tried to lift the trail. Got it up. Set it down. Moving it for any distance is at least a 4 man operation. 6 would be better.
