.308 FTR bullet weight and twist choice.

I got a JCC barrel made up for the new Sierra 200's for this year. It makes shooting out at distance alot easier then the 223 70gr and 243 105gr I was using before, thats for sure.
 
TrxR the KP bullets and the new sierra 200's need a different throat and chamber than what jugs are setup for if you want them to group well and be consistent I've been trying a lot of new combinations and a 9 twist works best for those long bullets as well as a different lead angle and groove configuration

What groove configuration and leade angle would you recommend? Been meaning to contact you for a barrel. Feel free to PM me. Thanks.
