Mini-30 firing pin?

Hello,
I have a mini-30 and I would love to use the cheap Russian ammo but I heard that using a power spring will make it more prone to breakage using the cheap Russian ammo, but Is it possible to buy a spare firing pin for the mini-30 and hold it under a torch for x amount of time, to harden it?
To some how heat treat it better?

You can get an aftermarket pin as Ruger does NOT sell them.

Also, the aftermarket pins leave a lot to be desired as far as quality.

i suppose you could try cryo treatment.

how cheap? gold and silver bear works just fine and is >.25 round.

also dont hardend the pin that will make it brake. you want to make it softer. which may or may not lead to bending. changeing the hardness of a metal is not just as easy process as people make it out.

I could be intrested in how they are cryoing. most companys that cryo are complete BS. and being ruger useing good stuff to start. not sure how much true cryo will help you.

the best way is to find out the Idea hardness needed then stress relief the steel. and make sure you keep the same hardness.

Perhaps, I should look at the hardness of the AK-47, or the SKS firing pin and use that as a example.
I'm not sure what company's out there would not BS me, but I would be very interested in how they could help.

True, that is cheap, but I would like to use whatever ammo comes my way as opposed to just using one or two brands.

From material science class what "cryo" metal does is push out impurities. yes it works to a point. there are quite a few problems with cryo. if you have a "big" impurities in "deep" in the metal and you cryo it a few things can happen.
1. start a "big" crack internally.
2. create unneeded stress of the material.
3. nothing. (this is the best of the worst.)
other things I seen is with chromemoly steel it will increase hardness of the steel. small bit like 59 to 60 hbr.
metals like aluminum are completely unaffected.(waste of money)
If you want to relief the internal stress is though heat treatment. I would have to look up proper for SS. you can Google it I bet. the short is you slowly heat it up to some temp; and leave it there for a time ; then slow cool it at some rate. this is normally in a oven of sorts. this done right will not change the hardness.
now for normal steel this will be a waste of time and money. steel will work harden over time and create stress and increase hardness. I think SS does the same thing.
which is why Cryo and heat would be a waste of time and money.
finding a titanium firing pin would be the best way to go.
I'm betting ruger is using a hard firing pin and that why they crack. looking at tolerances they may need to do that. (guessing)
I would have to have a long talk with them to "fix it" that I bet they won't talk to me about.
fire what you want if it brake ruger had great warranty

2 bs statement
1. A green company and metal. There full of it.
2. Why heat treat it if cryo did anything it the heat treatment that doing the "work". which brings me to green. How can they be green if there waste energy to cool it.
I would love to see there IEEE test.

I dont know, making a metal part last longer? Surly they don't use the energy and resources required to make the metal parts they are treating??
I just posted the 300 Below site because many on this site have sent their older Mini's and will swear that it stopped the stringing. Cheaper than a strut too.

Can't blame them for saying they're green with the nature nazis out looking to crucify companies. 'Crucifying' EPA Regulator was Eager to Inflict Pain | National Legal and Policy Center

Can't wait for hole green fad to die out. They waste more energy then they save but that hole different place then here to talk about.

I'm not going to say there system doesn't work.
its like have your car go in for oil change and they do it 3 times. And you pay for it.
it the heat treatment part that make it better not the cryo.
Call me old but I don't like company that lie or do unneeded work. Life to short. Do job right the first time.
See where im going.
Yes heat treatment works. But for a pin only so much. But maybe all that needed.

less then a strut. Hmm I be scared of what there doing. Gas any forum not cheap. And there thing said 72 hours. One well pay person for 72 hours for a company is 104 bucks hour. That cost for everything person only see 14-25 of it

problem is I dont. And want to so I ask questions and try to figure it all out.

It upset some but I dont care. Knowledge is power. And in this time maybe all that matter.

I can only see one question in the following post and there isn't even a question mark next to it.

I must confess, I don't see where you are going. All I see is someone wanting to call someone a liar but doesnt want to??
At least the 300 Below site has a page dedicated to the research of their claims.. others, not so much.

In my opinion, being a skeptic for the sake of being a skeptic is a waste of time. Life is too short.

From what I got from there site. 20% of what there doing is work you want 80%is for show. Why they do that I dont know. I don't want call them lie. I have found in business a lie what business men are teached to do. Some do it to explain complicated things to people that dont understand what it is there buying. 90% of the world fits this.

Some take advantage of this and are out to rape people. I dont think we have a Enron company here but they are telling a good story.

With that said. Feel free to spend money how one sees fit. I just hate for some one to fall for a story.

I don't see a problem with trying out the cryo processing, as long as the price is right, hell it might even work.
other wise, what are my alternatives?

well i got some time to look at there patent. My opinion stay away from them. Find your self a real black smith have them heat treat your parts.

If you dont belive me go to your local college with a material science class sit in it or just read the book. you can look up cryo and heat treatment. and you will find out why i say stay away.

there site had no standardized testing to prove or back any of there statements.
what they show is articls from othere people research in generic format.

untel i see standardized test of any kind or at lest some sort of intelligent infromation about what they do.
the patent told me enought to scare me.

stay away from them!

This a company that i google and in one of there news articals had more tech data about they cryo treat ment then the hole site of below 300.

cryo is not issue. its real and does work. just like heat treatment.

the problem is when you do it wrong or dont know what your doing. it can create problems.
IE your paying some one to mess your stuff up.

Ill be honest greywolf the best thing you can do email ruger with your concern and do what they say. they make the gun they know it better then any one you will find.

I beat if you ask ruger enough they will free of charge replace any fireing pin you brake for normal use. this i bet will include use of any ammo you put in your gun.

Well,
I didn't see anything that would give me an idea of what they would charge money wise, so I called them up and was told to call back Monday.
Can't wait to see what they say.

The problem with going to Ruger is the rifle is custom, I'm under the impression that they will not touch a custom gun.

That is also a interesting idea, I plan on buying another pin and having it cryo or maybe I should just send it to a black smith.

custom gun? how custom? if its all out yes your right.
if its just a stock or "muzzle brake" then they will fix it no problem.

Find a good black smith or machine shop. i dont know where you live but im sure you can find some one near you that can make you one and clearly explane how they heat treated the pin.
if your lucky you can find one that will due titanum and you will never have another problem.
