22 LR

[pop pop]

My Marlin Mdl 60 22LR  quit cycling Subsonic ammo this morning. Over the past 3 days I have been covered up with gray squirrels. They have cost me about 3,000.00 not counting the inconveniences they have caused in getting repairs done. I have had to close my garage doors because they were attacking the inside of my garage. 

The CCI subsonic is a little softer on the ears but mildly underpowered ammo, and I went to it for the extra quietness is has. The MDL 60 has been cycling it very well only a failure to cycle once in a few weeks. The last 3 days it will not fire 4 rounds without stoppages. I just took it down and cleaned the stuffings out of the brl and chamber and lubed it and left it wet. It seems easier and smother when cycling it by hand now. I haven't cleaned it in several months, and hope that was my problem. I probably have 800 to 1000 rounds through it over a period of 8 months since cleaning. We will see down the road.

Are you talking about the CCI Quiet-22 Segmented HP?  I've found those to be highly effective on tree rats, and in a .22 bolt gun they're quieter than my RWS Diana pellet rifle.  I've never tried the ammo in a semiauto but it does seem to burn dirty so I guess it's not surprising if it wouldn't cycle reliably after a while.  Hope the cleaning helps.

Many a troublesome semi-auto .22 has been repaired by nothing more than a good cleaning.

I can't even begin to count how many .22 rifles and pistols I've seen that look like they were never cleaned!  The little Marlin model 60 is a fine rifle, but a bear to clean properly!  I've scored some real bargains on .22s that looked like the bore was worn out, but were just leaded.

I am using CCI Sub-Sonic 22 LR 40 gr Led H P Small Game ammo. It is just a tad quiter, but this new ammo I just got out says rated at 1050 FPS. That seems to me that it would not be sub-sonic. The old ammo was 36 Gr Lead HP at 750 FPS.

I shoot the CCI Quite in my old pump actions and it is super quiet. Definitely quieter than a pellet gun. With a can it’s stupid quiet.

Shot the 22 twice this morning. Missed the same squirrel twice. Rifle did fine but the operator needs to stop rushing the shots. Hope the rifle continues to cycle after the cleaning and lubing and the operator settles down and uses better skills.
