Interestingly, I got an email from Starline this week announcing they are making 6.8SPC brass now. I’ve only used SSA brass for that caliber (haven’t loaded or shot any in a few years) but they got bought out by Nosler if I remember correctly.

This thing just screams for a build using a Proof Research barrel, say 20-24”. I would also be interested in seeing if any 5.56 suppressors will be rated for it with longer barrels.
