Pictured above: Pieces and parts for a batch of T7 actions of various sorts. The complete action is a T7/17 - .177 caliber action. The first chronograph pass put it at an average of 1078 fps with Crow Mag pellets. A little more tweaking to the newly designed valve brought it down to a more realistic average of 1020 fps with the Crow Mags, and mid 960's with Crosman Premier Heavies. There now exists a working prototype in each caliber - .177, .20, .22, and .25. The barreled breech in the center is a .20 for a T7/20 TDR action. That paticular action produces mid 850's with some sort of Beeman .20 pellets I have on hand. This site was created and is best viewed in 1024 X 768 screen resolution |
