The cartridge show on the top of the link page, looks much like the Remington Viper/Yellowjacket, truncated cone rounds.
It seems a few years ago, there was a firm, somewhere in the northwestern states..Montana, idaho.. that started marketing those cartridges. I got hold of some of them at that time.. They were OK, but not outstanding.
I've been a CCI fan since they were new, in 1960s.. ...But I am not exclusively CCI, I like Hornady for my .17 HMR.. even though they may be loaded by CCI..
