Saturday, I was taking pics of some rugers that I'm selling and had to move the Seville out of the safe. It seems to be getting more and more purple every time I get it out. Took a pic just cuz I like it.   |

Is that the same phenomenon that some of the older Rugers have?

Yep, same thing. The best explanation I've seen on "plumming" is straight from the Ruger Forum: "There are six reasons for guns to turn "plum". First is the temperature of the bluing salts, which must be maintained at exactly 292 deg F. If the temperature is lower, bluing won't take properly. If the temperature is just a few degrees too high, parts will turn plum. Second is the concentration of the salts. Because water boils off, the salts tend to get too concentrated so bluing tanks must be equipped with a water replenishment system to keep the salts to water ratio at 10:1 (10 parts water for one part salts by weight). If the mixture gets too concentrated, parts will turn plum. Next is "time in the tank". If parts are left in the bluing tank too long, they will turn plum (1/2 hour is normal). Bluing salts do "wear out" so they must be replaced fairly often. When salts start aging, gun parts turn plum. Last is the alloy. Some alloys require special additives to the bluing salts or the parts will turn plum no matter how well you maintain the tanks. In most cases, parts will turn plum right out of the bluing tank. When alloys are the cause, it may take several years for the plum color to show up. I can't fault Ruger for alloy issues during the first few years of production but after that, there's no excuse. Several years ago, it was common to see a brand new Ruger SA with plum parts ... so the alloy was not their only problem. I think Ruger was "guilty" of several of the above issues but they are doing much better now (same alloys)" -Lee www.singleactions.com |
