I’m not concerned for classes at the VTC if this ammo is around 3000fps. So long as it is not M855 or some varient of 193, it is cool. The main reason for the restrcitions is for mobile classes where we get close to steel.
So buy the cheap stuff. Mediocre accuracy? Who cares at CTT ranges?
Just an fyi in 16 inch guns Wolf gold .223 is faster than PMC XP193. At least in a Troy mid length LwRCi m6a1 14.5 inch, and a Colt 6920. Kind of why I’ve been stocking it up. Loaded up 110 mags with this stuff before I left for my wife to hold off the Zombies.
