I already load supersonic for a 7.62x39 CZ 527 and have read that loading this cartridge as subsonic can be somewhat more dangerous due to the possibility of "secondary explosive effect" (SEE).
Just recently discovered that there is a kit to turn a .223 CZ 527 into 300 BLK. I'm wondering if the risk of SEE is as great for 300 BLK. It seems like low load density increases the possibility of SEE, but I think that the 300 BLK case capacity is lower than 7.62x39, so maybe that diminishes the chances of SEE?
Really just wondering if subsonic loading of 300 BLK can be considered safer (or substantially safer) than subsonic loading of 7.62x39. Any thoughts on the matter would be appreciated. Thanks!
