Ammo choice.
1. Standard Pressure , 40 gr, LRN.
I prefer lead, no copper plating.
Winchester T-22 is a old example, there are others by other mfgs.
I prefer Fiocchi, with CCI being my second choice for my guns.
My guns like this load.
2. Winchester Dynapoints.
If you can find these, these are standard pressure, with a dimple, not really a HP
3. Target grade ammo by Eley, RWS and others.
Your gun will inform you what it liked best.
Shot placement and quick effective hits are what one has to have, with any firearm, in any caliber.
Period.
A gun has to feed, extract feed - repeat.
Magazines are part of the semi auto design.
Guns are mfg to shoot ammunition of certain specifications, and are regulated to shoot point of aim/point of impact (POA/POI)
It does not matter what mfg makes the gun, platform, caliber, if the gun does not feed, extract, feed, repeat, shoot POA/POI , then one is not going to get shot placement in the first place, much less quick effective hits.
I don't care if you have umpteen bazillion rounds of the most hi-tech, most popular round, if these do not work in YOUR gun, you are screwed.
Bulls-eye shooters are a very smart bunch.
Everyone is so damn down on these folks, as they are not "hip, slick, cool and tactical enough".
Youth is wasted on the young...
Standard pressure is the best kept secret in a .22 firearm. Always has been, still is.
Reliability is a big factor, many hyper velocity shells, such as Stingers are NOT recommended for some guns.
One the OAL is different, and second the wear and tear on action and the dwell time is affected.
Bigger and faster is NOT always better.
Fast bullets often times start out fast and slow down fast and trajectory is off, and varies in a wider "window".
Part of that is do to dwell time.
That wear on a semi, will change how the round is chambered.
Match shooters will use a "gauge" to measure every .22 round to get all the ones the same to use for a string.
.22 ammo , like any ammo, will behave different. So having the same specs every time, increases reliable feeding into the chamber the same and the dwell time being the same.
Art & Science...Brister was correct, and he knew this applied to not only Shotguns.
i.e Beretta 21 A in .22 lr.
I have never had a problem with this gun. Never!
Neither has others I know. Some are Undercover Cops, Body Guards and the like.
I/we know why folks have a problem with these and 98% of the time, it is NOT the gun.
Beretta knows how to make small tip up guns, it is rare for me and mine to have seen a faulty Jetfire, Bobcat, Minx and others.
These small guns, have to be respected - even in revolvers.
There is not a lot of room for levers, and all to move, one reason one cannot get a action job on these as they can a bigger gun.
Hi-Velocity.
Prefer LRN.
CCI Mini Mags, Winchester X22lr, and Win Power point.
In the old days, we did not have CCI here. PowerPoint had not even been invented yet.
X22LR, ran in every damn gun we shot it through, even Jennings and Ravens.
It might not be the most accurate, often times it was!
Federal made a similar load, forget the name, and since ATK has them now, not looked to see if still in the line.
That load did the same thing.
Fiocchi had one ( maybe still does) and that was one nice load.
Remington, w-a-y back when had a good load, I used it.
Remington does not make their .22 ammo and for us, about mid 70's Rem loads were avoided like the Plague.
Recently...Remington or whomever is doing their .22 ammo, is doing a really nice job.
The Standard and Hi-Velocity are really running guns and shooting accurate!
Now I really hate light loads and the heavy loads. 60 gr SSS don't do ...
Most 34, 36 gr won't...Except, the Old Federal Bulk packs.
These are old, 40,000 rds were bought at one time and these are the ones I and mine are using ...getting low.
That 36 gr HP, hi-vel, has baffled us in being reliable, and accurate.
One old boy has a old High Standard he shoots for Bulls-Eye and his gun likes this load better than Eley and other expensive Target loads.
I have run to the aid of another, given them a Marlin 60, a box of T-22s and knew the gun would work, even if I had not shot the thing.
LRN and in Standard pressure will work.
I have seen the Autopsies, and been in on the Organ Harvests.
My (one of) old Beretta 21A's is stoked with Fiochhi standard pressure LRN, an and is used by a UC LEO lady /Bodyguard type.
H&R 999 I had, is stoked with some 20+year old Win X22LR.
Fella has this gun...
Marlin 60s , one is using a new Remington Target load of 40 gr LRN, it has yet to fail and this gun likes it. It likes Dynapoints real well, and what it was loaded with forever, just we wanted to try these and were surprised.
NAA Mini, we only do the 1 1/8" barrel. We only use standard pressure 40 gr LRN.
Some of these are worn around the neck as they have factory lanyards.
If a lady is down, and hands are in places where they should not be, think of where a ladies hands are, and at bad breath distance going for an eye, into mouth or sinus cavity.
We do lessons on this, and the ladies know where sinuses are.
Sinuses are just holes in the skull. Get out your Anatomy book and look these up.
Physically limited folks, knocked down or our of wheelchairs use these guns, and snub nose .22 , 32, and 38spls.
Some of my Mentors were interesting folks. They shared about Cold War, Checkpoints and Restrictions.
Nobody ever made fun of them carrying concealed a Colt Woodsman, or Beretta tip up - in .22
For fun, they shot lit cigarettes, to extinguish the glowing end.
Daylight, low light, no light...they did this.
