I use one for a 204, 224 Valkyrie, 6.5 Creedmoor, 6.5x47L, 240 Wby Mag, and a 300 Win Mag. I have taken big game using it with the 240 and 300. Primarily it is used as a hunting rig with 3 rounds or so at a time on the midrange to bigger stuff and no more than about 10 at a time with some of the smaller stuff. I have no need for a FA rated can. It is light, and I can depend on it to shoot to the same spot every time I put it on. Like others have said, it just depends on what is important to you. It does get hot really fast.
