First let me say I already have a 16" blackout that I reload for. An I know there AR some strong opinions on non 5.56 caliber ARs.
Comparing loadings between the two calibers I can't figure out what the practical difference s between the two. For equivalent bullet weight it looks to be only a marginal velocity increase.
What I'm trying to figure out is if I should go ahead and build a 6.8 spc around a 18" ml black hole barrel or should I sell the barrel and plan to swap to an 308 AR if I need something stronger?
Anyone have any thoughts?
