I will throw my input out there...I have put around 300 rounds or more thru my 22NXS. I wanted something comparable to a 22-250 in a standard AR15 to hunt coyotes. I was skeptical at first and after consulting with Greg and Ritch I went ahead and went for it. Ritch just happened to have a barrel on hand, so I started gathering necessary components and dies. What some say about the brass and forming process...it is not true...they are speculating and further more don't know because they don't have the NXS. It is not complicated!
I am 100% satisfied with the performance of the 22NXS cartridge...it actually exceeded my expectations. Brass can be bought in bulk, so no need to worry about getting caught short handed. Once you set the die properly, running the brass thru the 22 Nosler dies is no different than running any other cartridge thru your FL die...yes, it is as simple as that. You then load the cartridge and shoot it...period! This is nothing different than what you normally do reloading your other cartridges. Simply size, prime, charge, seat bullet and shoot...don't know why some argue that there is some "other" multi step process involved.
If there is a down side to the 22NXS, it is #1) AR magazine COAL limitations(not really the fault of the cartridge) and #2) limited acceptable powders...CFE223 seems to be "the one"...in my testing, others seem to hit pressure too quick, so velocity suffers when it is backed down to acceptable pressure...remember, I was looking for 22-250 performance out of a standard frame AR15, so I had a targeted velocity in mind...this was a "purpose" built rifle.
I tried 60gr Nosler and 60gr Vmax and personally feel that there is too much bullet shoved back into the case to get acceptable clearance to reliably run the cartridge in an AR magazine...as stated, I personally don't like that much bullet seated past the neck/shoulder junction...others don't seem to mind this, but I feel like accuracy suffers to some degree...as well as eating up case capacity...just my opinion.
The 55gr bullets seem to fit the bill real well as far as COAL for the magazine. The 55 Sierra, 55 Nosler, 55 Berger Varmint work real good, are accurate and achieve very good velocity...3650+ range. My most accurate bullets have been the Berger 52gr Target and Berger 52gr Varmint...I ended up going with these two bullets for Thermal night hunting and they absolutely hammer a coyote! Both bullets are built on the J4 jacket and quite honestly perform the same on coyotes...the 52 Varmint may do a little more damage, but not much.
So yes, the 22 NXS is everything that Greg and Ritch say it is, it is simple to load for, it produces right at 22-250 velocities out of a standard AR, feeds reliably(not one issue!), is accurate and does the job on coyotes. When/if this barrel gets shot out I will have another...might just get another barrel from Ritch to put back anyway.
I probably didn't answer much in the way of the heavier/longer bullets, but feel that they just take up too much room in the cartridge for my liking.
There is one thing I would like to try and would not have a problem with investing in the barrel and being the scapegoat to try...I would like to try a slower twist(only offered in 8 twist)...since for me the 55gr bullet seems to be the max for my liking, I would like to at least see this in a 10 twist offering. I see no need to be RPM'ing the [beeep] out of a 50-55gr bullet when you don't need to...just my thoughts. (Hint)
