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?
Actually, no.and all the short mags
An article of importance..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).
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 never could understand the dislike some have for a belted magnum. What is the difference whether it is rimmed, semi rimmed, rimless, or belted??
I said nothing about changing interna ballistics, I just don't think people ought to buy into Belted magnums not being accurate. Example, how many national championships have been won by 300WSM as apposed to the 300Win mag, you might be surprised and I am talking about only during the time the 300WSM has been in existence.It's not a matter of "buying into it." It's simple fact. You can't change internal ballistics.
