This problem could snow ball to other gun manufacturers if the EPA is involved? I hope not.
Buy an old blue gun, apparently.Wow, With so many blue guns, this post scares the cra* out of me !
What's safe and recomended these days ????????????
I think you'll find that those are lead deposits rather than wear. If you get a lead removal cloth and work the front of the cylinder, that should come off
"As a rule of thumb, if you would be comfortable applying the solvent of your choice to the finish of your automobile, it will probably be safe for use on your firearm"
So like allergy testing, I'm heading out to my garage to put droplets of various gun cleaners on the trunk lid of my car and wait to see which ones lift the paint...![]()
During the 1970s Hoppes #9 contained benzene, described on the label as nitro-benzene. Benzene was discovered to be a carcinogen then it was removed from bore solvents including #9. I don't recall when benzene was dropped off the list of ingredients but I think it was gone by the mid-1980s or earlier. The succeeding #9 continued to contain petroleum distillates, kerosene, and ammonia. The benzene fee #9 did not remove leading nearly as well as the older #9 with benzene.
Recently, last spring or summer, in a thread on ammoniated #9 and nickeled guns it was posted that #9 no longer contains ammonia. I went to the store, read a #9 label, and sure enough, ammonia was no longer on the list of contents. I did not buy it and have not tried ammonia free #9.
I had not seen this thread and presumed Hoppes had dropped ammonia because of the persistent belief that ammonia harms nickeled guns. Ammonia is in many bore solvents because it reacts with the copper in the fouling left by jacketed bullets. However, ammonia does not react with nickel and S&W never under plated with copper, so, despite the rumor, ammoniated #9 did not harm nickeled S&W revolvers. I think I now see the reason Hoppes dropped ammonia: whatever process is being passed off as bluing today.
I realize this thread was just drug back out of the archives after being inactive for four months so this question might not be spotted by the OP and others who posted in June, but what vintage of #9 caused the damage to your new blued S&Ws?
The problem is not the process but the alloy that use to make the barrel and cylinder. The carbon steel frame and yoke has the normal bluing precess. The EPA has nothing to do with it.
If cylinder gaps have to be fitted, isn't it likely that the cylinder face alone is cold blued and easier to strip?
No. Cylinder gaps are set by filing the barrel extension.
I recently received a SS gun back from S&W, reworked for cylinder cramp, and the cylinder face had clearly been milled.
What the H is cylinder cramp?
