The problem with new-fangled cartridges is always three fold.
1.) They are sold in lower quality new guns.
2.) Most never catch on, so you have some relic in just a few short years.
3.) They were built to solve a problem that didn’t exist in the first place or had a great solution already.
Modern history lesson?
.17 caliber guns from 17ppc to 17hmr to 17mach2 and a newer 17winchester. The only one that became common was 17hmr.
WSMs and WSSMs? I lost track honestly. Almost all of them are dead in only a decade, I can‘t remember which one slightly caught on amongst the herd.
6.5s. We already had 6.5x55 and 6.5 mannlicher. They had to make the 6.5 grendel. Then everyone had to have the 6.5x284 as the IT gun about 12 years ago. Now its the 6.5 creedmore. There were piles others too. 264 win? The list is long. In a hundred years, the 6.5x55 and 6.5MS will still exist, and probably the Creedmore.
6mms? 244 remington? 50 others that have come and gone, all copying the 243win that is the survivor.
7x57, 284, 7x61, 7x64, 280, 280ai, 7mm Rem, 7mm STW, 28 nosler, a new 280AI that isn‘t compatible with the old 280AI, etc. (7x57, 7x64, and 7mm Rem will survive...all the others are hiccups in the annals of history in 20 years)
