Standard vs regular velocity

[lolkopter]

Hi all

I have a CMMG ar 15 22LR conversion kit and a AA glock 17 22LR conversion. My CMMG has eaten pretty much any ammo I use, but the AA is very picky and only cycles with mini mag CCI.

My question is this, if I were to get a dedicated 22LR pistol or rifle is the only safe bet to get bolt action to use any ammo? I have a ton of CCI standard velocity and federal bulk. I just fear investing in a cool gun and then not working

My 10/22, SR22 and MKIII 22/45 run pretty much flawlessly. Of course a bolt is not going to be finicky, but a good quality semi will run well even with federal bulk if kept clean and lubed. Federal bulk is decent stuff.

I believe Standard is the regular velocity. But the most common velocity today is High.

Subsonic, which also includes "target" or "match" loads, at nominal speeds below 1,100 ft/s (340 m/s).
Standard-velocity: 1,000–1,135 ft/s (300–346 m/s). Common velocities are around 1,125 ft/s (343 m/s).
High-velocity: 1,200–1,310 ft/s (370–400 m/s) per second.
Hyper-velocity, or Ultra-velocity: over 1,400 ft/s (430 m/s).

Mini-Mag is a High velocity ammo.
Most bulk packs are High velocity as well.
Target ammo is generally Subsonic or Standard

Most modern semi autos will need high velocity to function reliably. But many will function with standard.
Its hard to give a blanket stamp of approval because sometimes two of the same firearm will have different ammo preferences that that individual firearm prefers.
Best thing to do is just test each of your firearms and see what they will run reliably and accurately at the price you can afford.

The Federal AutoMatch is listed as 1200 fps, CCI SV is 1070 fps, whereas CCI MiniMag is rated at 1235 fps. I would think that the Federal should have enough umph to cycle the Glock. Might just be that kit just doesn't like the Fed. As you said, the AA kit is just picky.

I'm currently running 2 Marlins (795 & 60), an old Colt Huntsman and A CZ SP-01 w/ a Kadet kit. I've shot all of them using each of the rounds mentioned and have never had an issue. They don't all perform the same in each weapon, each rimfire seems to have it's own preference.

Doesn't have to be bolt action

Bolt, lever or pump action will eat up anything you feed them. Revolvers will do the same.

Thats because you don't have to worry about cycling issues, which most .22LR pistols have...and even tho the cheapest bulk 22 ammo may cycle and function in your firearm, doesn't mean its the most accurate. Most people probably do not care about being super accurate, but it is worth mentioning.

Good to know thanks guys. I saw a lot of threads recommending guns, but couldn't find one on this question :-)

My 10/22 was sent to Clark 15-20 years ago, I still have a brick or two of Federal gold medal match 22lr I bought back then it likes it and shoots great with it.
I've yet to find a 22lr it won't shoot, but the Federal GM match is really accurate in it.

Take a look at the conversion kit.

Can you polish the rails where the bolt slides and other friction points???

I have shot and old colt woodsman that really only fed copper clad ammo

Some firearms are more finicky than others.

If you can smooth out the friction points on the cmmg then you allow more of the recoil to move the bolt to the rear vs fighting friction.

This helps with better ejection and more velocity on the bolt to strip the next round from the mag and chamber the round.

Try cycling a few rounds by hand. Pull the bolt to the rear and release it.

Do the rounds show marks indicating scratches from the magazine?
Any scratches from the chamber on the conversion kit?
Do the bullets show any dents from a hard struck on the feed lips?

Subsonic/standard-velocity ammo should work in just about anything. If it doesn't, go to a lighter recoil spring.

Hi all

Interesting about your AA ( Advantage Arms?) kit. I just put one on my Springfield XD and am very impressed with it. Recommended ammo is CCI Mini Mag 40 gr. BUT it has handled several different brands of 40 gr High velocity ammo PLUS a couple brands of 36 grain Hollow points. What it DOES NOT like is Western, made by Olin-Winchester 36 gr Hollowpoints, neither does my Buckmark they don't feed any better in it. I think it has to do with the shape of the bullet? I was surprised that it would handle the other 36 gr hollow points. ANY Winchester Brand is not recommended by AA per the litrature that came with my AA XD kit. The Western is now religated to revolvers and bolt action rifles.

No reason a CMMG, TACCOM, or DPMS will not cycle standard velocity. All mine do.
The exception is Remington. The profile of the bullet can cause feeding issues and is very dirty. Nearly no manufacturer will recommend it.

Hey OP (and those of you that have the AA Glock Conversion Kit),

I have had the AA Conversion Kit for my G23 for a few years now and initially had issues with it being picky with ammo. Anyway, a while back I found this mod to the mags which fixed the ammo issue. See the following link and scroll down: http://www.glocktalk.com/forums/show...1009833&page=2

I did this mod to all my AA mags and the kit has been 99% reliable and feeds, fires, cycles, ejects most .22LR ammo that I've fed it including Remington, Aguila, CCI, Federal and Winchester bulk ammo (with the exception for Aguila Super Colibri and CCI Quiet-22 for obvious reasons and an occasional round that I suspect may be defective from the factory). Anyway, good luck and hope this helps.

My HRA .22LR lever action rifle takes .22 Short, .22 Long and .22 Long Rifle. The first two have lower velocities than standard (1,070 fps) so I would say that is a good bet to get as well.

It's a good gun, classic looking, and my kids and nephew like shooting it.

Good luck!

Until my unfortunate boating accident where I lost all my 10/22s, I had 5 10/22s. All of them worked flawlessly with Federal Bulk 525 Blue Box and any other ammo I tried. The subsonic rounds are not recommended for semi autos, but I have never tried them in my 10/22s. (Before I lost them, that is.)

Ruger Mark Semi Auto pistols and the SR22p also work perfectly with Federal. I have shot many bricks of this stuff through all my .22 semi autos and it works perfectly. Out of thousands of rounds I think I have had something like two failures-to-fire (dud rounds).

Remington Golden also works fine although it is somewhat dirtier than Federal.
