For example, my trust owns a Templar Ark30, but their original design. According to the company owner, when I asked him in an email, for .223/5.56, I should not use the can on a barrel shorter than 12.5" (this is for the original design, not the new ones). Now, I could probably get away with a shorter barrel, but the can is not designed for it and it would likely kill the can over the long run. Failure might not be immediate. Could be a few hundred rounds. Maybe thousands. I'm not going to find out and will just stick with the boundaries as expressed by the manufacturer.

Next can will be SBR rated for sure.
Oh sweet, it says my can is SBR rated. There was no info for my pistol can in terms of SBR rating but I have to assume that's meant for shorter barrels in the first place. Did learn my pistol can can actually handle subsonic 300BO which is interesting.
