I have some old rifles around. One is an old Springfield 84 C- (yes that is the way it is marked). It is a .22 that has been in my family since I can remember and came from my Granddad.
It it a heavy bolt action.22. I imagine in it's day it was the cat's meow.
Here are some pixs



I have shot it many times since I was a youg'un. Yes I always 'cleaned' it. You know, run the bore, brush the bolt, wipe it all down.
Well it had a really crappy 6 stage creepy, gritty trigger. The gun is VERY accurate and if ya learned to shoot on it you also learned how to overcome BAD triggers.
Well I have never been one to tear down guns as I don't know a lot about 'em. That is until I bought a milsurp Ishapore that came in cosmoline and had to be ripped down and scrubbed.
Sooooooo...... I figured 'what the heck' give it a bit of a try on one of my favorite guns. So I separated the stock from the gun (one thumb screw) and got out the mineral spirits and a tooth brush. Took all of 10 minutes to scrub it up well, blow dry and reassemble.
The trigger now has some 'free slop' (even when cocked) and is MUCH smoother. Yes, still a little grit and creep but it is much better.
So bottom line to 'newbies' (like me). Don't be afraid. Don't 'over do' it by disassembling things ya don't know (getting out a punch scares the hell out of me!) but go ahead and get it to the lowest level and maybe even one lower than ya ever did before. CLEAN IT with some mineral spirits or break free etc., dry, oil and you will be AMAZED how much better that old gun feels!
