Cleaning with screw-in chokes

[stubblejumper]

I believe the Muller featherweight chokes have a ceramic finish which is probably much smoother than a raw metal choke . I have had a set of 2 Muller chokes for 6 ish years I have never cleaned them any more than what they get when I clean the bores .

I have the Muller Stainless chokes, with the same ceramic coating, and they stay clean, and never come loose, when hand tightened.

My Muller Featherweight's will come loose if I don't check them from time to time, I use grease on the threads and that helps a lot. I'm in the habit of checking them fairly often and if I snug them up by hand when the barrels are hot then they're too tight to loosen by hand when the barrels cool... first world problems I guess. Just have to remember to loosen them when the barrels are hot and leave them loose in between shooting days.
The lack of plastic build up is due to the ceramic coating I believe. It seems like a good system but you have to be careful with harsh cleaners that might discolor them and do not drop them on the cement floor or you could chip the ceramic!

I do check the chokes regularly by hand, but they don't come loose, that may be due to the expansion rate of the stainless being different than that of the aluminum in the lightweight chokes. I have never used the wrench that came with the chokes, I just use anti seize, and tighten by hand.

I believe the majority of choke issues are from folks tightening them too much. They have a very fine shallow thread which can be easily overstressed. The pitch is such that they are self locking, meaning axial force wont cause the choke to rotate. I believe expansion and contraction can often cause a choke to become slightly loose over several shooting sessions, I just check them every once and a while. Never had a problem...

I think your correct.
