Yeah, some of the so called "obsolete" calibers are really cool. Some that are getting scarce are pretty cool too. I have dies for several that I want to add like the .22 Super Jet, .219 Zipper, etc. One of the reasons I have to reload is the odd stuff that I like to shoot. Some of the obsolete stuff is better than the calibers that replaced it. Many only lost due to marketing campaigns. Look at the creedmoor garbage out. Purely marketing. It can't outperform the .260, the 6.5 Saum, 6.5x55, and man others; but because people buy into marketing it sells well.
