It does make me laugh when folks piss and moan about a belt. It’s really nonexistent to me.
My bitch with belted cartridges isn't the belt per se, but the amount of slop that is often present in the fit of new brass to chamber even when both chamber and brass are within specification.
Yeah, that is an annoying mystery. .0091" to .00261" between the cartridge and chamber is built into the SAAMI specs for the 7mm Rem Mag, 300 Win Mag, and 350 Rem Mag, etc. You can't fix it until after the initial firing.
