Rifle is new out of box and stock with no mods other than the barrel swap . Rifle was tethered and regulated and bullets were all sized to .2495 and 10 bhn . Shot the rifle with the stock 24 inch barrel first . With this barrel the PW needed to be turned up all the way to 13 to perform at its best . With the 48 grain bullets 2400 psi was its best setting at 2500 psi it dropped off . With the 62 grain bullets 2500 psi was its tops . I next removed the barrel and installed the 32 inch barrel with all settings being left as they were with the 24 inch barrel to get a accurate difference that the barrel would make . Next I took the 62 grain bullets up 100 psi at a time to 2900 psi with a gain that the 24 inch barrel could not do . Then I dropped the PW setting down 1 turn at a time too 3 and really lost no energy . Were the 24 inch barrel needed all the spring tension it could get . Might be more in the rifle with a little more playing with the TH but I think I will leave it a lone and enjoy it as is for a while . Marvin
