The 224V is probably a better AR-15 round than the 22N. Mag length, factory ammo with the heavies.
Long freebore, longer than mag length handloads, and the 22N can take advantage of the extra powder.
You are sort of limited to what you can fit in a normal AR-15 compared to a bolt gun or AR10.
Putting together a 22 Thunderbolt would be interesting.
The bad press of one and done pockets, ripped rims, swipes, and the horrible 18" barrels offered early on made the 22N a red headed step child from the get go. Youtube users that couldn't get the 22N to shoot didn't help either.
I think gas issues reinforced the claims of soft brass. To me soft brass would be indicated with imprints in the head at reasonable loads, not swipes. I don't see that. There are some bullet weights and loads that can be used at mag length but for my primary use long loads give me even more powder space.
I don't normally take it but I do have a 22" (ARP 3R) upper I can swap in for mag dumps. OR even a 223 upper or two

Spare 5.56 and 224V bolts and I can swap from the 22N rebated rim to the 22 NOSGAR.
Seems dropping the NOSGAR loads by about 1 grain gives similar performance due to the heavier cases.
A few years ago I bought the last three boxes (50round) of HAGAR brass from Creedmore, and the last three from Powder valley and so far three 500 case boxes from Creedmore. Still have 22N factory ammo to make once fired cases and a few hundred Nosler and Dogtown brass. I expect brass supply to dry up and the cartridge to become even more obsolete but I'm set for a while

. This winter I will watch for another 20% off sale @ X-caliber and buy another barrel to replace a long-in-the-tooth one I now have with throat erosion. I load the 88s 040 off @ 2.520" Still shoots pretty good at about 2500 rounds.
Recent 100yd target. Of course it's a cherry picked group.

Obviously the 22N is not very popular but if someone can shoot a mile with the 224V, why can't if be done with the 22N? One day, maybe
