I just got a used R9 and chonoed it yesterday with the following results(3 shots per pellet type at 5' from muzzle): Sheridan cylinders 518,511,530; JSB exacts 614,628,617; Beeman FTS 673,680,668; Crow Mags 648,642,652. This was less than I had expected so was wondering if this is normal for a stock R9 and also what any of you have done to increase power and what were the results? Thanks, Ryan
