A mate asked me to have a look at his Raider 2 shot as accuracy was not good. Had a good go with it and at 15 yds its pellet on pellet then one 3/4" high right then one low. Cleaned the barrel, changed the scope, removed the silencer, removed the 2 shot mechanism, but still the same.
Has anyone any ideas as i'm bam boozled by this unless there's a land in the riffling thats broke.???????????
