Welcome to the site where the owners and members have had it with playing "nice" and being "inclusive" and "tolerant" of points of view that are destroying the fabric of what made this country great. The members here are sick and tired of politicians of all parties lying, deceiving, stealing, and pretending they are doing it all for the good of the country while selling out to special interests who have the set goal of destroying this country. We have had enough of career politicians who use their office only for personal gain, and who refuse to listen to the people who put them in office. The membership is no longer part of the silent majority who play nice and get along while getting screwed by anyone with a loud voice and an agenda. We will no longer allow anyone to piss down our back and tell us it's raining. And we like guns too.

Default Have any of you used grease on firing pin spring

Had a question for you guys. Have any of you ever used grease on the firing pin (where the firing pin spring slides back and forth and on the firing pin spring itself) on bolt action rifles? I had gotten an Eddystone M1917 awhile back and I was having a hell of a time pushing the bolt home that last little bit. At first I though I just had to get used to the cock on close but after trying other peoples M1917 there just seemed to be something wrong with mine. I did a complete tear down of the bolt and there was old, waxy caked on grease all over the firing pin and firing pin spring. After soaking in kerosene for about a day and some hard scrubbing I got all the grease off and after replacing the grease with some oil the bolt throw home was pretty smooth as it should be for a cock on close gun. Afterwards though I got to thinking that while the lack of care caused problems with this rifle it seems grease could be a better choice on the firing pin spring. You hear over and over if it slides (which the bolt spring does) use grease if it moves use oil. If cared for properly and cleaned and re-greased every so often so it doesn't turn into a waxy mess it seems like it would be a better choice than oil. What do you guys think

That waxy caked on grease was probably cosmoline. I use GI gun grease on most everything. Just a light coat. For long term storage though, nothing beats good old cosmoline.

Thats what I was thinking. Being how old and waxy it was it looks like something done by the government for long term storage and at some point it was sold to a civilian and never wiped clean. From doing some reading every country seems to have their own version of cosmoline. The Russians had, what we typically think of when we think of cosmoline, a brown waxy gunk. It seems the US Army long term storage grease was a tannish white gunk and that is exactly what this looked like and it smelled like melted crayons.

As for the original question I'm tempted to pick a guinea pig rifle and try it to see how it works. The positives I see is smoother spring action. The main thing seems to be to find the correct grease to use. If its to thin it will just "melt" off leaving your springs with little protection. If you choose a really thick grease it could be to sticky and could cause the spring to release at a slower speed then normal or really stick to the point it doesn't release at all. The other thing is weather. It has to be able withstand heat so it doesn't melt away and cold so it doesn't get so thick and gunky it causes malfunctions.

The bolt on my M1917 is as smooth as glass,open and closes with just. 1 finger.
How is that TW25b grease in cold weather?say below 20 degrees?

A very light coat of oil is all that is necessary on M-16 firing pin. If any...It is chrome plated...you know...

Grease will freeze solid in cold weather. A guy brought in a rifle that in cold weather went "squiiiiiise" and refused to set off a primer. In warm weather it worked fine, but in cold weather it refused to work at all. Dropped it in a pail of carb cleaner and guess what? Worked great in hot AND cold weather! Who ever packed it full of grease must have used a high pressure grease gun to pack it! A LIGHT coating of grease would be OK for warm weather, but for cold weather just put in a few drops of oil.

Not only that but mixing it with dust, blackpowder and other contaminants could give you a missfire.

Remember in the 90's all the stories about "fully automatic" Chinese SKS rifles?

It was determined that the problem was grease (probably Cosmoline) in the firing pin channel was causing the firing pins to contact the primers as soon as the bolt went into battery. A good cleaning was the fix.

I had one of those before I cleaned it.
