Unhappy High Standard supermatic citation .22


Registered Users do not see the above ad.


I have a High Standard supermatic citation .22 cal. Every 2 to 3 rounds it jams, the cartridge fails to fully enter the chamber. I was using CCI Mini Mag, Winchester high velocity, Federal target. Just wondering if it's the ammo, mag clip or what?

I have not owned one, but, if I had a .22LR that was jamming the first thing I would do is completely disassemble it and clean everything. Then lightly grease it. When I say completely I mean the magazine too. I would not grease the magazine, though I would lightly oil the sides so the spring glides easily. I would polish the cone/feed ramp.

note: I own (9) .22LR, I mean your particular model.

The Hi-Std Super Citation is a pretty old firearm. Had one I sold back in the early 70's that was bought used in the early 60's. My thoughts would be a weak magazine spring, or one that needs taken apart as recommended above and given a good cleaning. Might even try stretching the spring somewhat for more tension.

Might check out www.e-gunparts.com (Numrich Arms) for replacement spring.

I have a military model target version. I find that the less expensive brands of ammunition, promotional ammo etc, tend to jam periodically. That is because the chamber on mine is a tight one. Match ammo always works.

I used a HS supermatic in Vietnam for close quiet work. That pistol was labeled for L and LR. We used some special low muzzle velocity longs in those days and they did not always work the action with the muffler on it. That drove us to looking into what was going on. We had been snapping the pistol dry. That is never a good idea for a .22 rimfire. It curls a lip on the entrance to the chamber and occasionally causes failures to feed properly. A good gunsmith can take care of that in about five minutes. Brownells sells a tool to do it.

I'll bet that the failures to feed are magazine related.
Notes about adjustment from High Standard:
Quote:
* Magazine feeding is very sensitive to the particular ammunition that is being used. Due to the wide variance in ammunition specifications, the width of the magazines feed lips must be adjusted for the particular target ammunition to be used to obtain maximum reliability.
* The basic dimensions should be .230 wide for the rear of the front lips and .185 wide for the front of the rear lips. The front and rear lips should also be kept parallel.
* Magazines should always be kept clean and well oiled.

NOTE: 1. The .230 dimension is fairly constant for all ammunition. The .185 dimension should be increased if the bullets are feeding too low, and it should be decreased if the bullets are feeding too high. This adjustment can be accomplished with tools like needle nose pliers. You can also make your own tool with a piece of 1/4 in.1/2 in. flat stock by sawing a slot in the end. 2. Due to the overall length of some 22LR match ammunition, it will be impossible to get it to feed ten (10) rounds properly.

CAUTION: 1. The magazine lips are heat-treated and will break if they are bent too much at one time. 2. Magazine feed lips may drag on slide feed rail if decreased in width too much.
Hope that this helps.
Pete

High Standards can end up with a cracked frame when using high velocity ammunition.
I only use standard or match with velocity of 1070 or less.
All is good...D.

Very good advice.
The cracks, if that happens, will most likely appear as hairline fractures at the top rear of the magazine well on either or both sides. Depending on the wear and tear, the gun can remain functional for many years but....avoid HV ammo.
