High velocity .22LR ammo in pistols

[bladeracer]

I've been curious about this for a while, primarily because pistol shooters will talk about not using "high velocity" ammo, and that we should use "standard velocity" ammo, despite standard velocity not being a fixed standard. Standard can refer to anything from around 1000fps to well over 1200fps.
Virtually all the .22LR ammo I've seen specifies rifle velocities, even pistol-specific ammo, and most "high velocity" ammo I've seen is likely to be subsonic from a pistol barrel - the "hyper-velocity" ammo is very likely to remain sonic from pistols.

With the 5.5" Ruger Mk2 I put 5rds of 1070fps CCI Standard over the chrono and got an average of 925fps ES26 SD9 (145fps slower than spec).
Then 5rds of 1260fps Mini-Mag HP for an average of 1127fps ES64 SD21 (133fps slower). This was just slightly supersonic, it straddles the sound barrier so some crack and some don't (we got 1028fps in a mate's 5" GSG1911 in November which is well subsonic).
Then 5rds of 1640fps CCI Stinger for an average of 1296fps ES69 SD22 (344fps slower).
Then 5rds of 1850fps CCI Copper-22 for an average of 1346fps ES152 SD52 (504fps slower). One round was very low at 1245fps. Excluding that one the mean would be 1372fps and ES38fps.
The Stingers and Coppers were impressively loud for .22LR cartridges, the 21gn Copper has very light recoil despite the velocity.

While I had the chrono out a mate put some of his ammo over it in his 6" Volquartson Scorpion.
The 845fps CCI Quiet Semi-Auto gave an average of 841fps ES36 SD13. I didn't expect this to cycle the pistol, but his Volq has a considerably lighter recoil spring than my Mk2's.
The 1080fps Aguila Target Competition averaged 967fps ES46 SD14.
And the 710fps CCI Quiet RN averaged 696fps ES20 SD7 - but did not cycle the pistol.

Where did you get the cci quiet semi auto?

The Aguila sniper subsonic has the heaviest bullet I’ve seen for a .22. It would be an interesting test but might not run in every pistol but it should be fine if the pistol runs quiet semi-autos.

The copper stuff flies extremely fast for a .22 but it’s also around 20 grains which is amongst the lightest I’ve seen for .22.

All in all, I’ll use the CCI Standard.

Yes but from memory requires about a 1:10 to a 1:11 to stabilize because of the projectile length

Hmmm...InSeason Warragul I think.

Good point, I've been meaning to try it in a pistol. The issue with it is the bullet length is marginal for stability in the standard 16"-twist barrels.

Yes, I don't think I've seen a lighter .22LR bullet than 21gn. The solid copper bullet doesn't deform in any material I've recovered it from.

CCI Standard is best for sure, but none around this area currently.

I think they specify 9"-twist, but it shoots well in my Norinco rifles, and I think they are only slightly tighter twist rate than the standard 16"-twist.

Interesting. Haven't visited that store yet but ive heard good reports.

I like them, and they're open on Sundays.

Not a pistol but I use cci mini mags and cci stingers in my smith & wesson M & P15-22 semi auto and they work fine.

In a model 41 S&W .22 we looked after for some friends applying to keep their grand-dads gun, we ran everything through it, the bulk box HV stuff, down to Aust made Win subs. It had two barrels with it and both, short and target, ran it all without a hitch.

And I must say, everything runs through our 10/22's. 40 and 42 Win subs, HV's, Stingers, Velocitors etc.
Except the CCI Quiet and Segmented quiets, they aren't expected to work at 700fps or whatever they are. And they are really, useless fad things for us.
Those rounds like the Aguila super-heavy things "suppressor" stuff, we aren't interested in, we really need just good performing HPHV and HP sub ammo on the farm.

Anyone use those 60g Aguila? They very smokey I find. I just love how they are 60g. So heavy for a 22.

Tested them just now in the Ruger MkII.
Spec is 950fps on the box.
783 767 764 798 769 Mean of 776 ES34 SD12
Group was roughly eight-inches across at 20m, but I wasn't trying at all so don't read too much into it. But the holes were not circular so they are tumbling. I doubt they'd be any good at all much further than 25m.

This is the ruger i just bought ...... I put a red dot on it

Off sand bags it shoots great at 25m this with win 555 bulk ammo

Now as for the trigger it would win a competition for the most atrocious breaks at nine and a half pounds has about three millimeters of creep hence this group did the best I could I have a Volquartsen trigger kit coming can't wait to try it then

I also tried the CCI Quiet Semi-Auto in my Stainless Ruger Mk2 as it has the heaviest bolt spring, and it cycled fine. Made 805fps.

My mate also tested in his 6" Volquartson Scorpion:
SK High Velocity Match averaged 1050fps ES52 SD17
SK Long Range Match averaged 971fps ES10 SD3
Winchester Subsonic Max 42gn averaged 1037fps (I deleted the string before recording the numbers but remembered the average).

Very nice, Deye243!

I bought a pair of Mk2's off an old member here (thanks Tubs) last year and finally picked them up on Monday. The blued one appears to be entirely untouched. The stainless one is improved - has extended slide lock and mag release, and has grub screws for trigger reset and over-travel. Trigger on the blue one is 2.5lb, the stainless one is 5lb. My mate's Volq Scorpion is 1.7lb. I've shot a Standard match this morning and a 25m match on Wednesday with the blued one so far and Rose's brother shot a Standard match and a 25m match with the stainless one today. I'm hoping next week I'll find time to shoot both off the bench to see how good they each are. The stainless one also has fibre-optic sights which I'm not sure are allowed in ISSF matches.

I have always liked the ruget pistols they are simple even the old mark one is very simple to take down clean and put back together I still don't understand why people complain about it once you work out how to do it doesn't take any longer than 10 seconds .

[Willie]

Have two Ruger pistols. One a MKIII and one a MKIV. Neither of them really like cci standard ammo but both like Eley standard.

I haven't had one apart since the early nineties, not really looking forward to it, but I haven't even looked at the pistols yet. Cowboy shooting today - left home at 0640 got home at 1545. Big day, but fun

[deye243]

Putting it back together is all about the Swinging dick assembly that's the nickname we gave it and once you nut that out you can do it with your eyes shut

I watched a video and it does look pretty simple. I have to chronograph some .44-40's and .357's so I'll try to put a few hundred rounds through the Rugers tomorrow as well. the swinging dick is similar to the Luger reassembly.
