An excellent article. Although I don't reload at this point, I have enough general knowledge that it was quite understandable for me. However, I've never heard of a belted cartridge before. If it's not too much trouble, would you mind explaining it to me please?

It is on some magnum cartridges like the 300H&H, 300Win mag, 300Weaherby (all Weatherby cartirges), 8mm Rem Mag, 375H&H and so on. Some believed it was put there for strengthening the case to make it stronger, but it is for head spacing and for sure feeding out of a box magazine.

None belted case like this 7mm08

Belted case like this 8mm Rem Mag case

note belt around the bottom of the case.

Okay. I guess that the higher the pressure of a load, the more important the head space. Is that right?

Marlinman 12-13-2012 05:42 AM

Yes it is ca. Anything magnum in a rifle is usually belted I.e. 7mm rem mag, 338 win mag, 300 win mag and all the short mags

Actually, no.

Winchester Short Magnum
Quote:

All of the WSM cartridges are based on the .404 Jeffery non-belted magnum cartridge which is shortened to fit a short rifle action (such as a .308 Winchester).
An article of importance..

Pros & Cons of the .300 Magnums
Quote:

The belted case was a British idea that originated with the .400/375 Belted Nitro Express in 1905, and it was later used in the development of the .375 H&H and .300 H&H Magnums. Since the .400/375 and .375 H&H cases have virtually no shoulder and the shoulder of the .300 H&H is long and mildly tapered, the British figured all needed a belt for positive headspacing, and they were right. Magnum-size cartridges, such as those developed during the early part of the 20th century by Charles Newton, were exceptions, but other magnums that came along after the 1920s had belts on their cases. While the belt was unnecessary on most of those cartridges, it spelled high performance to many hunters, and for that reason it sold lots of rifles and ammunition through the years. Then came a new breed of magnum cartridges without a belt, and suddenly that little band of brass just forward of the extraction groove of a case had more critics than Michael Moore at a soap-makers convention.

I don't like rebated rims nor short fat bullets, but that is a preference of mine and it mainly has to do with feeding from a magazine. Some like them I don't.

I never could understand the dislike some have for a belted magnum. What is the difference whether it is rimmed, semi rimmed, rimless, or belted??
