I forgot about the rebated rim on the RAR, it has been a while since I looked into, and quickly away from, that cartridge.
The SOCOM line of cartridges are fantastic for their ability to neatly single-stack and feed from any unmodified AR-15. Almost everything else is a compromise. I tried and tried to get .45 ACP to work in a standard magazine by only adding a spacer to the front wall, it would have worked except the feed lips don't extend far enough forward, otherwise the .473" cases do work pretty well with standard feed lips.

I just happen to run a 30 Herrett Rimless AR 15 upper (trimmed back 6.8 SPC case) as well

At large, whereabouts unknown.
I still mean to do this, but haven't got around to it yet. I bought dies, does that count as a start?I just happen to run a 30 Herrett Rimless AR 15 upper (trimmed back 6.8 SPC case) as well

From top to bottom
308 Win with 150gr Spirepoint
308 Win Case
308 Win trimmed to 41mm (308x1.5”)
308 Win first form
308 Win neck and shoulder formed for 7.62x41
308 Win inside neck-reamed and final trimmed
7.62x41 final formed and loaded with a 110gr RN
My great idea....has been thought of before. A decade ago a national champ in Benchrest Rifle developed the .30 BRX from the .30 Benchrest for use in 300M international use in a bolt rifle and the gunsmith who developed the 300Blackout about that same time tried to develop a 30BRX AR15 upper at the same pressure levels as the bolt rifle (55PSI) but it didn’t work well for him as it required a thickened upper receiver and a high-strength bolt which made it too $$$ for commercial use. That said, I intend to develop the 7.62x41 load as a 30-30 Winchester equivalent and same pressure levels (42K PSI limit - also due to the 450 Bushmaster AR5 bolt I'm using) which would mean it outperforms the 7.62x39 at least which the 7.62 Herrett Rimless was about equal to in performance in my 16" barreled AR15.
A slightly bigger cartridge and slightly more powder than my earlier post about my 7.62 Herrett Rimless wildcat (trimmed down and necked up 6.8 SPC) but with the 450 Bushmaster bolt and a 6.8 SPC magazine for my AR15, it runs pretty smoothly. Some days, you don’t need the fastest and hottest cartridge to be an effective deer and pig cartridge. Now I actually do have a "30-30" AR15
(and forgive the jacketed bullets in the pictures. I'm doing cast loads in the next round of testing.)

I created a separate post in the Testing section of the forum and will update that thread with target and velocity numbers when I can get to the range again. First run to the range was for function testing. next will be for more data.
I'm looking forward to seeing what you find with the 22 Nosler. Are you going to be developing a load with 69 or 75gr cast lead bullets also?

So have ya decided??
Ill re enforce the suggestion of a 300 BO. (But a 7.62x39 would do equally as well)
I just love the lil 300. Accurate miserly on powder and very light recoil. Subs are a blast too even WO A moderator.
I just shot a ladder yesterday with a MP 314-140 HP and aa1680 For cast it shot Very well!! But you can see by my acc test lod it can really shoot better than ya would think. If ya have been doing this long aughta blow your mind that 400$ buys ya a HONEST 1/2 MOA RIFLE!!

With the virus and house quarantine, it has been decided for me. No $$$ coming in means fewer going out. If/when the new normal stabilizes, I will pursue this. Or not. I just learned that some of the Remington rimfire bolt actions can be converted to 32 Long.

70~77gr bullets are my "target" weights. Going to start with some 55gr because I don't have the heavier weight pills in hand. Cast sometime later.

I've got the Mihek 65gr Mold from a group buy a few years back if you want a bunch to try. They are already .225" sized, checked and 2x polycoated in case you want to amp up the velocity during testing. I use them in my 223Rem AR15 and my .22-6mm Rem Mauser. After gas-checks and PC they weigh about 68gr

I will try and fond the thread where I read about the conversion. There are some Remington rimfire rifle wih a multi lugged bolt which can be used. I think Ed Harris used a Model 788 but that is heavier than I want to go.
