[QUOTE="barreltwister, post: 591159, member: 14826"] Today we chronyed a 280AI that my son had built a few months ago. Didn't have time to play with it much before the hunting season. 140 TTSX's run from 3312 to 3333 fps over at least 20 rounds. This with Rel22 in a 24" long 9" twist Shilen #2 barrel. [/QUOTE]
