Paul......You're a Field target trophy man. Have you found them to be to tight in any of your barrels? I've spent a bit of time over the weekend testing pellets in each rifle properly and the underlevers like AA Diablo fields and the Break barrels most definitely prefer FTT's. Is this something you've found too? Interestingly in the TX200 .22 the difference between FTT's and AA's was over 2ft lb on the chrono.
