akbound,

I remember when they came up with that "not so bright" idea. They also claimed it added more strength to the base of the case. Some called in "magnumized".

That may be true, but let's call it what it "really" is/was!! It's a selling ploy, that really did nothing but get lots and lots of folks to buy into the "magnum theory"!!!

As for headspace on the belt. If anyone took the time to measure a number of cartridges of several brands, it's easy to see that "most" of the belted cases really "headspace" on the "shoulder" instead of the belt, just like non belted cases!

Well, the belt served it's purpose, it made a lot of folks buy "belted magnums"!! I guess for "that" reason, it wasn't so bad of an idea.
