I got a new 10/22 at Wally World. I looked down the bore with a bore scope and it was clean, and took it to the range. It didn't feed right. Not with 50 shot clip, 25 shot clip, or what really bothered me, the factory clip. My buddy the gunsmith noticed that the bolt was very sticky and rough. He suggested that my scope mount screws were too long, and rubbing on the bolt. So that night I tore it down, and the screws were fine. What wasn't fine was a lot of brown rock hard "grease" or something all in the action. I cleaned all that out, mostly by chiseling it out with a flat blade screwdriver. The bolt itself looked clean, but I ran it under some super hot water for a while just to make sure. The bolt now worked smoothly. A couple days later, I decided to see if it fed right. I tried to chamber a round. Shell would go mostly into the chamber, then stick. I pushed the shell forward with my finger, slid right in. Tried to extract with the bolt many times. No luck. I rack the bolt to see if it will grab the case. *bang* Hole in livingroom ceiling..!!! Set unsafe thing aside. Next weekend I take it to the range. Try to feed, same problem, same *bang* every time I let the bolt fly home. I take it to the guy that owns the range. He tears it apart including the bolt and shows me how the bolt is totally full of the rock hard brown grease, and the firing pin was probably stuck out extended. I'm now soaking it in mineral spirits hoping to get it working right. The tiny spring under the FP has me concerned. Not sure if it just lays there under the pin or what. Why didn't Ruger use cosmoline or something instead of brown superglue to lube new guns with? I know some of this is my fault, but still??? I just had to vent.. I've bought dozens of new guns, and never had something this ugly out of the box. One more problem and I'm going to sell the sucker for $100 just to get rid of it. - Joe
