Talked to Ryan today from Barnes and it looks like by January, they will have a 200 gr TTSX in the .308 cal. Yes, it will be boattail and not flat based. The bc will be .540 I also exchanged several emails with im regarding his/Barnes thoughts on the Berger Bullets. He kept it very professional but did give me some very good info and insight comparing the two bullets. If anyone is interested, I can PM them the email.
