Don't see a point with .300BLK gaining popularity.
The 6.8 produces a lot more power than a 300blk. The BLK is slower than the 7.62x39 with bullets of the same weight.
Perhaps. When would you rather have a 6.8 than a 5.56, .300BLK, or .308, though?
For the price, just doesn't appeal at all, to me. If you want a special snowflake cartridge, I'd go 6.5.
