Just bought a CVA Kodiac. I went to the range to test fire and sight-in. I was using45 cal Hornady 250gr SST sabots, and can't get them down the barrel( the barrel was cleaned between each round fired). I tried some 232gr powerbelts and they slide down the barrel with almost no pressure. Does anybody out there have any suggestions as to the possible cause of the trouble I'm having?????[:@]
