I've used my Trident, CAC45, and Triple-X Warrior. The Warrior is listed as a .223 can, but the aperture in the baffles is large enough to handle a .30 caliber, and (when still in production) and manufacturer stated that they could easily handle up to full-powered .308. It is essentially a .30 caliber can with 1/2-28 threads.
Of the three, the Trident is quietest, and the CAC45 and Warrior sound about the same. Since the Trident is shortest, lightest, and quietest, it's a no-brainer which one for me to use.
