Why not 8208 with the 160TTSX? They worked well for me and velocity was good.
I did try that with this rifles previous barrel and it worked well. 2900FPS and good accuracy. At the time though, AA2230 was really fast and really accurate (those Barnes loads may be a bit sketchy...). I plan to re-try the 160s with 8208 and with Benchmark though. Just started with H322 since I hadn't tried it before and it's a faster burning powder than 8208. Edit: Nirvana in the 338 Federal would be a temp stable AA2230. Really gets great velocity and accuracy with 160-185gn bullets.
