I am not sure what is wrong with Mag 2. The feed lips appear to be set at the same angle as the other mags and the spring seems to have the same tension. For shooting groups I was loading five into the magazine. The FTF occurred most often when the third round was being fed into the chamber. Possibly the follower is getting hung up somehow in the magazine. I haven't tried to disassemble the magazines yet.

All shooting was done at 25m in an indoor range seated resting my elbows on a table.
I had removed the scope so I remounted it and re-zeroed it with 10 rounds of CCI Velocitor. No failures.
POI Test
I fired ten 5 round groups using Mag 1 and Mag 3. The barrel was removed between each group and then reassembled to the receiver to determine if there was a significant change in POI from removing the barrel. There was a slight change but I am not sure if this is from removing the barrel or my shooting. This test needs to be repeated with a proper rest. 50 rounds no failures.
Groups 1, 3 and 6.

Dirty Rifle / Dirty Ammo Test.
I have collected a pile a various .22 cartridges from a clubs misfire box. There are different manufacturers, Bullet weights, and bullet types, Lead Round Nose, Copper Plated, Copper Plated Hollow Point, Truncated Cone Hollow Point, etc.
The misfire box is metal with a lot of rust and the powdered rust coats the ammunition. I did a cursory inspection and removed any cartridges with dented cartridge case or damaged bullets that would obviously prevent the cartridge from feeding. I used Mag 1 and Mag 3 loaded with eight rounds and the rounds were selected randomly out of a bucket. I fired them in a rapid but controlled manner then reloaded the magazines as quickly as I could and fired again. The only other break was to clear stoppages. Of 80 rounds loaded, 77 fired successfully with 3 Failure to Feed, 1 Failure to Eject were the fired cartridge case remained completely inside the action and 3 Misfires. One misfire had a previous firing pin strike the other two had not been previously fired but I tried each twice and they did not fire. Two misfires were round 1 and 2 of the last magazine so I thought the rifle might be getting dirty enough that the rounds were not fully seating in the chamber. I loaded the mags with 14 rounds of CCI Velocitor and the cycled and fired without issue except for the very last round which failed to feed.
Totals
Range Trips - 6
Round Count - 673 (577 rounds since the rifle was cleaned if my notes are correct)
Failure to Feed - 40 (Mag 1 - 3, Mag 2 - 33, Mag 3 - 3)
Failure to Eject - 13 (Mag 1 - 3, Mag 2 - 9, Mag 3 - 1)
Misfire - 4 (Mag 1 - 2, Mag 2 - 0, Mag 3 - 2)
Failure Rate - 8.47% (failure rate is decreasing now than Mag 2 is not being used)
This test will be continued until the rifle fails to function. I still have a pile of dirty ammo.

The rounds on the left and right are Lead Round Nose. The colour on the bullet is from the powdered rust.

Dirty Rifle / Dirty Ammo Con't
Hit the range again tonight and ran 27 rounds of Winchester T22 Standard Velocity through the rifle without a failure then 138 rounds of ammunition recovered from the misfire bin.
Had 18 Failure to Eject, 1 Failure to Feed and 3 Misfires. The Failure to Eject included 7 rounds where the round fired and cycled the action but not far enough to strip the next round from the magazine. Recoil was noticeably less than most other rounds and for three of the rounds the empty cartridge case was re-chambered. The one Failure to Feed was due to the bullet being bent in the cartridge case. The bolt was forced into battery and the round fired.
Of the 19 FTF / FTE 13 had Winchester Headstamps, 3 had Federal headstamps, and 3 are unknown. Of the 3 Misfires 2 had Winchester headstamps and one had a Federal headstamps.

It's not as bad as some of you guys think. When I took mine to the range I usually shoot 200 to 300 rounds through it continuously. No speed mag dump though. It survived all those trips and mine hasn't fall apart or self-exploded yet. In fact, the trigger finally seems to lighten up a little after 1500 rounds. Depends on your ammo, mine is still pretty clean after each trip. Nothing much to clean up compare to my 9mm blow-back carbine.
It does jam/FTF/FTE but happens to all my 22lr guns.

That's a pretty good video.
Survival does require reliability. However, I feel my stats are a little misleading. Most of the failures are a result of Mag 2 which I believe is defective even though I can't find the problem. Unfortunately these magazines can't be disassembled easily. I also believe that some of the initial failure were due to the rifle not being broken in.
On range trip 6 I fired 10 rounds of CCI Velocitor and 50 rounds of CCI Stinger with 100% reliability. On range trip 7 I fired 27 rounds of Winchester T22 with 100% reliability and I have issues with this ammo in other semi-autos.
Most of the failures on range trip 6 and 7 is ammo related. The cartridges from the misfire bin are dirty, many have damaged bullets from being jammed in the chamber of another firearm, some the bullet is bent in the cartridge case and some are misfires. I am using this ammo because I have been told that this rifle will jam after 100 rounds if it's not cleaned. By using the crappiest ammo I could find I am hoping to see how dirty I can get the rifle before it is unusable. It looks like I will run out of "dirty ammo" on the next range trip.
That describes my experience with the old Charter Arms version.Worst gun by far I have ever owned.Not with me anymore RIP.Inaccurate and unreliable.That gun couldn't even hit a standing rabbit at 15 meters.It would misfire and the critter would run away.It was a toy gun that shot real bullets sometimes.
Dirty Rifle / Dirty Ammo Done
Fired the last 143 rounds of dirty ammunition and had 9 failures to eject, 9 failures to feed, and 1 misfire which fired on the second try. 7 of the failures to eject had Winchester Super X headstamps, one had a Federal headstamp. Several of the rounds had obvious damage to the bullet and a couple had small dents in the cartridge case.
Then I ran 128 rounds of new ammunition (18 x CCI Mini Mag, 2 x CCI Stinger, 28 x Federal 40gr CP Solid, 40 x Remington Golden Bullet and 40 x CCI Velocitor) without a single failure.

One night this week I'll strip the rifle down and see if there is any excessive wear or damage to any parts. The trigger has smoothed out a bit but is still fairly stiff.

that made me laugh!
Stripped the rifle down and cleaned it. Quite a bit of carbon and debris in the receiver. The bottom of the bolt had a thick layer of carbon. The bolt has some wear marks on it. The hammer and trigger had less wear marks on them than I expected. The front of the hammer is silver from impacting the bolt and firing pin but is still in good shape.

I took Mag 2 apart. They aren't made to be taken apart. You have to bend a small metal tab down from the bottom of the magazine and then the bottom of the magazine can be bent down so the spring and follower can be removed. The follower had a rough spot on the front, like ripples in the plastic. I sanded it smooth with 600 grit sand paper.

Hit the range again. All shooting was indoors at 25m seated with my elbows resting on a table. The scope has been removed and the sights were used.
Fired
- 100 rounds CCI AR Tactical 40gr Copper Plated Round Nose alternating between Mag 1 and Mag 3 - no failures.
- 30 rounds Federal 36gr Copper Plated Hollow Point all with Mag 2 - no failures, maybe sanding the follower worked.
- 24 rounds Remington Golden Bullet 40gr Plated Round Nose, 8 rounds from each magazine - one failure to feed with Mag 2
32 Rounds CCI AR Tactical

24 Rounds Remington Golden Bullets - wearing my glasses would likely improve the score on this target as I had a very difficult time seeing the outline of the squirrel.
