Hello just joined and not sure how to post but my new model 41 is very difficult to cycle even with target Federal 1200 fps .22 ammo can anyone recommend a make that works I have shot about 300 rounds so far.

Try CCI Standard Velocity.....
M41's can be a little finicky and you may have to hunt around for something it likes. Be careful with any High Velocity stuff. It can batter the gun more than you might like.


(Just pray that it doesn't decide it likes Eley Tenex or similar..)


I just noticed that you only have 300 rounds through it. That's not even a good start on break-in....)

My 41 cycles with any standard velocity 22lr ammo, even Winchester and Remington.

Thanks for the quick reply from you both
I was given a few rounds of sv CCI and was worse than what I had sometimes half ejected round and new round get stuck in breach so do I just keep going with the Federal until it wears in or lighter 6.5 lb spring

Now that I am paying, CCI standard velocity. When Uncle Sam was issuing, RWS R50. It shot well with government white box, but guaranteed one or two dead rounds per box of fifty.

For reasons I've never understood, Model 41s are notorious for (potentially) being finicky about ammo, and each one is a law unto itself. CCI SV seems to work in most guns, but now always. I'm fortunate because mine will run with just about anything, but that's not always the case. I'd recommend trying the CCI and giving the gun some time to break in. If that doesn't solve the problem, then your only option is to try as many brands and types of ammo as you can get your hands on and hope to find one or more that work well.

CCI SV is the ONLY ammo my 41 will cycle reliably

Load a magazine with ten rounds; place a drop of RemOil on the top round. Load and shoot. You may only have to do this once - you may have to repeat the process several times to break in your Model 41. It WILL work though. Ask me how I know.

As some above state, IN GENERAL, CCI Std. Vel. has proven to be about the best in M41's. Not just for reliability but I find them to be the most accurate as well.

I bought my Model 41 three years ago, and experienced a number of failures to extract and failures to eject even when using CCI Standard Velocity. These failures caused failures to feed. This all stopped after I had approximately 1500 rounds through the pistol.

I currently shoot about 100 rounds per week through the pistol and am not experiencing any stoppages.

Hang in there and keep shooting. You also may want to clean your magazines once in a while to remove all the variables. Ask me how I know this.

Hello , when Walmarts in Candad stoped selling ammo ,I went to as many as I could and bought all the bulk 22 Winchester I could find . I knew that it would bauk in my Mod 41 .So a the range I sprayed on the cartridges " lyman case lube "before loading in to the magazines . This was done on the bench
,on a pape rtowel ,just a handful at a time . I used this for the 10,000 rounds I bought . This also cured several 22 auto rifles known to be jam-o-matic . this is also done by some bulls-eye shooters to avoid jams on timed and rapid fire events . Hope this helps .

I am on my third 5,000 round case of CCI Blazer in my two M41s. There is no slide battering with standard recoil springs. CCI Blazer velocity is ~1025 to 1050 fps in my M41s , not the 1150 fps listed on the CCI website. Most 22 LR velocities are listed in a 18" to 20" rifle barrel.

My guns don't function reliably with CCI Standard velocity ammo. At $4 a box my wallet wasn't too happy either.

EDIT: CCI Blazer 22 Long Rifle Ammo 40 Grain Lead Round Nose

Everyone has been so helpful I am going to try the lube and oil sounds like feeding problems and hang in there and get this gun worn in as it is new.
l had a model 52 38sp a few years ago ammunition was never a problem as I loaded my own, It seams to be cci standard velocity that everyone likes but what is cci blazer.

Don't forget to clean the factory preservative stuff they ship new pistols with, it's not a lubricant and can cause malfunctions if left in place.
Spray can of gun scrubber , brake or carburetor cleaner will help remove the stuff. Then lube it....I like RemOil on mine but any lubricant will do.

Blazer is CCI's High Velocity plinking ammo (?almost bulk?) It's a couple hundred fps faster (give or take) than Standard Velocity.

Blazer is like Federal ammo, both are produced by CCI-SV. CCI owns a lot more ammo companies but is the best ammo for the M41's and M46's as well. My 1958 year model M41 will not cycle any but the CCI-SV ammo thru it or just jam up. I also get the best accuracy from it also.

If I understand you, high velocity ammo will not cycle the gun. That being the case, lower velocity ammo will be even less likely to do so.
If the gun is used, you may have a dirty chamber which could use a good scrubbing. Also use a wooden toothpick to remove the buildup of dirt under the extractor head and in the circular groove in the breechface. If a new gun, you may have an undersized chamber which would require reaming by a gunsmith or at the factory.

I went round and round with my 41. Just when I thought I had it beaten into submission, it would start failing to eject. I tried a bunch of different ammo, various spring weights, a new extractor, lubes, greases, extreme chamber scrubbing and probably some things I've forgotten.

CCI Standard Velocity had been the go-to ammo; for everybody else! Didn't work for me. Then one day I tried Eley. Not the high priced stuff, just Eley target. I use it in my CZ 452 for long range silhouetee. My 41 worked flawlessly with the Eley ammo. It's all I use now and has not hiccuped once. As a minimum, I shoot 90 rounds of it through the 41 every week at the Friday night pistol league. It turned a picky pistol into the superb pistol I expected it to be. Now if only the ammo could turn the shooter into a superb performer . . . .

if its new send it back

My M41 gets CCI SV for Steel Challenge, Aquila SV for plinking.
No problems until last month I cleaned it as thoroughly as possible from field strip. Took about 25 rounds before it would function reliably.

High Velocity ammo only beats the heck out of the M41's and M46's. The spring tension in a M41 is set for CCI -SV ammo. It makes sence to me as it works in the vast majority of M41's and has for many years as well. Plus they are cleaner burning powder and much more accurate then many others as well.

A few years ago, a S&W employee told me that 41s were set up for CCI Green Tag ammo. I never see it around here, though.

I read that Green Tag was just selected lots of SV.

I AGREE THAT THIS ROUND COUNT IS TOO LOW TO COME TO ANY CONCLUSIONS---ESP WITH A .22 CALIBER SEMI-AUTO. THIS PISTOL NEEDS TO BE BROKEN IN. THERE IS NO SHORTCUT, LIKE DRY FIRING.......

IN MY 60 YEARS OF SHOOTING--INCLUDING 3 DECADES OF BULLSEYE COMPETITION--I HAVE SHOT JUST ABOUT EVERY BRAND AND TYPE OF AMMO AVAILABLE, FROM BULK JUNK TO HIGH END "MATCH" AMMO, INCLUDING CCI STANDARD VELOCITY, AND GREEN TAG......

I HAVE SETTLED ON CCI MINI-MAG, 40GR SOLIDS, EXCLUSIVELY, FOR USE IN ALL OF MY .22 CALIBER FIREARMS. THEY ARE NOT HYPER VELOCITY, SO THEY DON'T NEEDLESSLY "BATTER" A SEMI-AUTO. THE BULLETS ARE COPPER WASHED, AND MUCH CLEANER SHOOTING THAN LUBED LEAD BULLETS. THEY HAVE A MINISCULE FAILURE TO FIRE OR EJECT RATE---LESS THAN 1 IN A BRICK OF 500. THEY ARE VERY ACCURATE IN MY RUGER MK-II, GOVERNMENT TARGET MODEL, AND EVERYTHING ELSE THAT I SHOOT......

IMHO---THEY ARE WORTH A TRY IN YOUR M41......

I may be real touchy, but I used to hate being next to someone using HV during a Bullseye match when everyone else was using SV. I found the extra volume of the HV rounds distracting.

Kind of: bam, bam, BANG!, bam, bam, etc........

I agree with one eye joe.
I bought a new M41, PC last fall. The manual says
ammunition to use is .22LR. The gun is made for 22 LR, no battering. From the 1st shot out of the new M41 till now, CCI Mini Mags. Never once had a problem of any kind and they are very accurate.

Due to competition, a M41 is expected to fire a lot of rounds. If the Mothership thought anything but Standard or Low Velocity was needed to prevent battering, they would say so to cover themselves in event of a warranty issue......Nope just 22LR, your choice.

Model 52

The CCI-SV ammo should work the best in your M41. Remember to put a drop of oil on your slides and down by your safety before every shooting session. I personally wonder if there is a problem with the angle of your extractor which could cause these type of issue's.

Another vote for SV ammo, and a drop of Rem oil or Starrett oil on the top round of the magazine. I also use EEZOX on the slide rails. EEZOX is a lighter fluid like consistency lube that dries up. Use sparingly as it spreads thin and not much is needed. It also doesn't gum up with powder like oil does. I still wipe the outside down with an oiled cloth for protection.

Aguila SV ammo that I tried is pretty anemic, a bit dirty, but was accurate out of my 41. I did have cycling issues that were cured with a lighter Wolff spring. I used the heaviest spring out of the kit of 5 or 6 springs that would cycle reliably.
When I try new ammo, I go back to the factory spring. CCI SV always works well, Norma Match and the Federal Automatch or 711b have been solid performers too.
