I see it as a great marketing ploy by Remington,the 221F, ,while a good cartridge itis dead, since they have the tooling set up for the brass and probably have a ton of brass on hand someone there came up with necking the it down thus reviving the 17 machIV...changing it litte and calling it the best little 17 to come out since sliced bread.
What is old is new again! just my $.02
Well of course it is! Isn't everything? I can tell you this though the 221 FB and the 17 Mach IV or two of the absolute best prairie dog guns ever. If someone asked me pick two rifles and only two rifles to go to the dog town those would be them or possibly the 20 VT (which is a 221 FB necked down to 20 caliber with improved shoulder) might nudge out the parent case. The problem is that the small bore guys, and varminters are a very small market share. There are a few of us die hards who love them but we are few and far between.
