You're right - it matters not a whit that it has a belt.

I'd just not rather have a belt on a case that does not need one, is all.

If this case needs a belt - so be it - couldn't give a rat's ass one way or the other. I don't like the appearance of this new case so would never buy one - even if available here which is unlikely.

This is simply an oddly designed case for a modern round. Don't need it.

I have rimless rifle ctgs., one with a belt as well as rimmed case rifles. They all work perfectly, feed perfectly & shoot just fine.

The belt on many rounds is simply an advertising scam. It is not needed (but on a few ctgs.), but many people have sucked up the adverts that a belt is needed for strength on all so-called magnum rounds. Many these rounds have the same working pressure as a .220 Swift or .22-250 (.22 Varminter), 1930's rimless or semi-rimmed cases. Other rimless cases operating on the same pressures as the 'big BELTED magnums' are the 6mm Rem. and .270 Winchester, for example.
