Disillusioned with Ruger MarkII

The only jams I have had were when I failed to clean mine thoroughly. I allowed dirt to build up in the extraction groove at the rear of the chamber. After scraping it clean with a toothpick, the jams went away.

Larry C, you refer to serial # prefixes on the Ruger website. Where is that info? I have a Ruger that I would like to find the date of manufacture for.

Does anyone know if Ruger or another site can provide such info?
 
I have a 10/22 Rifle, I love the thing, but it jammed about every 40 shots. Then I changed the ammo, was using Winchesters, switched to CCI's. The CCI's were the cheapest I could find at $9 for a box of 500. Totally reliable. I got 1 jam after my 550th shot. I think by that time though, it was a "dirty gun" problem, instead of unreliable gun problem. So before you give up on them, know that sometimes, guns are picky about the diet of bullets you feed it.

I'm not defending the Rugers, I'm just saying that once in a while, you get a lot of problems and then you suddenly find the perfect ammo and your jam problems disappear.

I want a 22/45, so things like "new ones suck compared to the old ones" really get me concerned... But then again, the Trailsides cost so much...

Thanks everone for all the advice on my Ruger MarkII that I was so disgusted with with for jamming on empty hulls every few rounds.

This week end I went plinking with it and am in love with it again.

The problem appeared do be a result of my over lubing it with action grease. Apparently a little oil goes a long way.

I cleaned the bolt and housing with spray cleaner and put it together dry. It fired about 15 rounds and started jamming again. Upon examining it I found more grease had migrated around and on the bolt. After a series of firing and cleaning every few rounds, I was able to get all five of my magazines with standard ammo (even Remington's cheapo ammo.) thru it.

I had heavily lubricated down in the trigger area and the hammer linkage with Brownell's action lube. I never dreamed how quickly it would work its way into the bolt area. I don't know exactly why it would move so fast into the wrong area. Maybe the recoil or the the hammer helped throw some of it.
Anyway it works great now.

Thanks again for everones interest.

Upjohn and others who have had problems,

I purchased a MK512 a little over a year ago. Don't know manufacture date. Jammed all the time.

Like you I cleaned it out, keep a thin film of Hoppe's in general, magazines DRY and clean and, MOST IMPORTANT, a dab of Lubriplate on the rod in the spring on top of the bolt.

It now shoots HUNDREDS of cheap Federal ammo ($8.50 for 550 rounds) with no problems. CCI MiniMags group better, though.
 
Upjohn, sorry for the delay in processing your request for Ruger serial numbers for your MkII. My recollection was that it was on the factory website, but when I went to that site I found that it has been updated and the serial number section had been deleted. I tried www.ruger-firearms.com/prdcyr but was unable to access that site. I think the info you need WAS on the factory site. It's a shame, too, because it was a very useful service. Perhaps the book "Ruger and His Guns" might have it.
 
Upjohn:
I never lubricate my Mark II, and I've had mine for 15 years. I do clean everything with Hoppe's, but then I wipe it dry. I'd stay away from the lube.
