Does anyone have data for RL-17 and the barnes 168 tsx for the 300wsm. I have all of these components but no data.

Alliant lists 68 as a max with a 165. Others have reported that max really is max with that data. I'd start at 65.5 and work up looking for accuracy.
You should be able to get the same speed or very close as you do with other 165 class bullets.

I actually did read that on their site but I've heard that barnes has vastly different maxes witheir all copper bullets...any idea?
