I shoot Lapua in my 338 along with other brass. In my 6.5 I use Hornady. So far not had any issues people talk about (loose primer etc). Anneal after about 2-3 shots. Only questions for me will revolve around: Cost per round, availability and when released.

Will be interesting to hear testing results from folks. Sounds like at least 1 year before available (comment about Shot Show in Jan 2017 and then lead time to release).
