You could be correct, but to the best of my knowledge, I thought that the "CLE Match" chamber was the same as the CLE/USAMU chamber which is specifically throated for single-feeding the considerably longer 80gr SMKs for 600yd comps which won't work at mag-lengths in the AR. It is NOT the "CLE Chamber" which is a modified Wylde. Although the CLE Match is supposed to work well with the lighter/shorter match pills as well (at least the ones that aren't prone to problems with a slgihtly longer jump), I'd be damned sure to ask before assuming that you have got the "best" chamber specs for the job.
To that end, OP...best to confirm anything/everything with the fine folks at CLE before you order just so you are all on the same page as to exactly what you are getting and whether its the best option for you and your stated goals with your particular rifle/ammo.
