I just purchased one of these rifles on the recomendation of a couple of my friends. With the use of H 4227 powder and a soboted .45 cal hornady 250 grain bullet they have both shot 1&quot; groups at 100 yds. The cleanup can be done with regular powder solvents, and there is no rush because the powderis smokeless. I haven't shot mine yet but am looking forward to is.<font color=blue></font id=blue>
