Well, that rifle was sold when we divorced, so I haven't had my hands in one in several years. But, if I remember correctly, one screw, plus removing the barrel band, got the action out of the stock and it was fairly easy after that. Being a Ruger, the parts are simple and relatively robust. It's certainly no more difficult than the new Deerfields or a Mini-14. You won't need to disassemble the trigger group; just spray that thoroughly with carb cleaner once you get it out. The important thing is to get all the old powder debris and congealed lubricants out of the bolt, receiver raceways, gas piston/cylinder ass'y & slide, and magazine tube/cartridge lifter.
When reloading, I avoided "dirty" powders like 2400 and went with cleaner burning choices, so I rarely had to tear it down and clean the action. Same thing in factory loads too. I avoided ones that produced much smoke. The Hornady factory loads are clean burning. I never had a jam or failure to feed of any kind with ours. When I had my shop, the ones that were brought to me for "repair" were ALWAYS filthy dirty. I even had 'em come in full of leaves, twigs, and dirt, and one was full of mud. One was so full of crud that I couldn't see a borelight through the barrel, which was full of lint, leaf debris, rust, dust, dirt and congealed WD-40. He's lucky he didn't pull the trigger on it. I only ever saw two that a thorough cleaning and 240gr jacketed ammo didn't cure and those two had been abused terribly.
