On a centerfire rifle (Ruger MkII with Timney Trigger in my case) should one leave a thin film of oil on the trigger and sear engagement or should these be clean and dry. I have noticed that after shooting for a while the trigger pull seams to go up as the heat level goes up.

Always lubricate moving parts. And don't be afraid to occasionally take apart, clean and relubricate triggers.

Chuck---

The proper amount of light oil applied to firearms, if applied to a glass wouldn't ruin the whiskey.

That means a LIGHT coat......just enough to darken degreased steel.

Oil will hold dust and dirt. That equates to mud, not good. I will only use dry molybdenum sulfide (Molykote Z) powder on Remington and Shilen triggers. For Jewells, just squirting them out with Ronson lighter fluid seems to be the acceptable service procedure. YOu can see the evidence on new Rem triggers of moly powder on the sideplate from where they shot some through the observation hole, sear engagement lube.

Thanks for the info guys!
