US Special Operations Command has become the point of origin and point of sale for several .30 caliber and .33 caliber cartridges, plus the 6.5 Creedmoor and 6 ARC. No matter who makes the ammo, it is match grade (because it has to be) and there is no doubt in my mind the same specs will flow into the civilian market.
The research done by a Marine colonel showed hollow point match bullets can be used by US scout / sniper teams without violating the Geneva Convention rules on weapons. I don’t know if this increased the prices of 168 grain Sierra Match Kings, but that was a go-to bullet for the teams using modified rifles chambered in 308 Win.
