ok buster,
i use a super ten bull barrel and have found it will put pellet on top of pellet from 30 yards all day long,the ten shot mag is very easy once you get the hang of it and i have sausage fingers lol,took two rabbits within 12 feet of each other the second one never heard the shot ,very quiet indeed.the only draw back i have is that its a little on the heavy side but willing to put up with it because every thing else is sooo good hope this helps
