Hey Jeff, looks like your projects doing well. Have fun with it sir. Wished you could've met Don, he was a hoot, no doubt. Sharp guy with a great sense of humor. Of all the predator rigs I use that rear grip XP 17 FB is my favorite.
__________________ Steve Hi Steve, Just out of interest what twist rate are you using with your rear grip with the 17FB . Looking to have a rear grip put together, using Trail Boss at around 2200FPS. Using the Berger twist rate calculator, it says it is totally unstable. My 17FB 1 in 9 rifle shoots well with 20grn normal loads but doesnt group to well with TB loads. G
