Info:
I got a new/used Ruger 10/22 carbine. yeh

I downloaded and read the manual, cleaned, oiled, and lubed it.
Tested with 50 rounds of Winchester X22LR. copper round nose
6 misfeeds,

grrrr....
usually but not always the last round in the magazine.
2 brand new OEM magazines, misfeeds occured with either.
no fail to fires, no problems ejecting, great fun, tight groups.
Serial number lookup says built around 1985.
The gun sat in an attic for years, looks like new, it was very dry, but no rust.
The barrel band was cracked, I replaced it. Looks like it was just over tightened and cracked.
After the cleaning and oiling it seemed to function fine, dry
Any suggestions on how to correct the feeding problem?
Ideas and suggestions so far:
Range officer suggested trying CCI Mini-MAG rounds? but they have slightly less muzzle velocity and energy than the Winchesters I used?
I used light application of gold lube (slide grease) on slide and bolt and a bit on spring and guide rod is this wrong? Should I just use oil here on giude rod and spring?
If I got some grease on front of bolt would this contribute to misfeeding?
Maybe I just need to cyle a few hundred rounds through it to loosen it up?
Does this all sound right?
Looks like the gun may never have been fired except at factory maybe.
Should I order a new guide rod spring handle assembly or an after market one, or maybe just polish this one?
Should I sand the lip of the feed area just to de burr it or create a feed ramp with a dremel? OR leave this area alone?
Someone also suggested sanding the stock around the magazine to ensure its not sitting at the wrong angle.
Its too much fun to shoot, I want to get it right, safe and reliable so I can let my Dad shoot it, and maybe talk the wife into shooting it too.
Thanks in advance!
I was using box marked Lot number 3XN311
hmmm just saw this:
Olin Corporation, through its Winchester Division, is recalling several lots of rimfire ammunition.
SUPER-X® HIGH VELOCITY (Symbol X22LR) and POWER-POINT® (Symbol X22LRPP)
Lot Numbers containing Letters: XN, YA, YB or YC
I Will try a box of CCI Min-Mags next Sat. Hope this solves the problem.
