I think that is gun nuts are a fickle bunch. When a new cartridge comes out we have to try it. Some make it and some are found to be just a rehash if something we already have. The 10mm started out big and then faded but now it is chambered one more guns than ever. It is my favorite round and I have found it to out perform the .45 ACP +P significantly especially hunting. If you want a powerful .45 the .460 Rowland fits the bill but it is a much cartridge. The .327 Federal is getting more popular. The .480 Ruger is another one that fills a need for hunting. With it and the 10mm I believe I could hunt anywhere in the world.
