Just sharing some info that I hope some folks will find useful. This site is obviously dedicated to NRA Highpower Rifle. However, there is just a wealth of articles on many topics, including springs. All of them are in PDF format and free to download. http://www.zediker.com/default.html I have a Ruger Mk I standard 22 pistol that I bought new in 1974. Today it is pretty much "Kentucky Fried"--parts is parts--to include a SS AMT heavy barrel top end. I managed to snag the AMT before Ruger took offense and legal action--"I say lads, I believe that's our patent you're infringing on". Recently I had begun to notice a sharpness in the recoil, metal contacting metal. Obviously, the bolt was starting to slam into the bolt stop pin. So I got on of these kits-- https://volquartsen.com/inventory_configurations/1086 I simply installed it as it came with the standard weight spring. I went to the range and tested it out with this ammo-- https://www.brownells.com/ammunition/rimfire-ammo/superextra-high-velocity-ammo-22-long-rifle-40gr-cprn-prod82595.aspx?avs|Cartridge_1=AFF_22+Long+Rifle&avs|Manufacturer_1=aguila Flawless function, no more metal on metal. My main point is that this kit DOES in fact work for the MK I, even though Volquartsen does not list it.

By "regular tumbler" I assume you mean vibratory. I cannot speak to that. YouTube is your friend. I have used a Thumbler's vibratory with walnut shells for decades. I still use it for brass that just needs a "touch up". That said, I got one of these-- https://www.youtube.com/watch?v=IaiuYqWLIbI --and love it. Here's another video with some good tips, especially the Armorall. That is what I now use. https://www.youtube.com/watch?v=6kSPu0x29HQ From my experience--- Armorall---Adding too much hurts nothing, but is a waste. Ideally, the solution should still be a little sudsy at the end of the cycle. Lemi Shine--Adding too much is also a waste, but will turn your brass pink(ish).
