28" 6.5 SAUM here on my Mausingfield. Shoots just like any other Bartlein, Rock Creek, etc.. I've had. Sub 1/2 MOA, no issues with heat that I've noticed so far. POI shift with a can is a little more than what I noticed with my 22" .260 barrel, but it is 6" longer so I'd expect a little more deflection from strapping a pound on the end of it.
