Just a reminder when you are looking at your equipment for up coming year, REPLACE your firing pin spring. If you have not replaced your firing pin spring in last two years or you have over 3000 rounds on your firing pin spring REPLACE it. It is the most import part of action and gun performance and the springs we use for Stolle actions is only 8.00. You really can not afford to not change the spring at that price and you would be surprised how many guys say rifle came alive again after the spring change. Stay away from speed springs and use what the manufacture uses.

I believe what Jim is saying here is the truth. How much is the entire assembly these days..for a Panda?
 
Sorry...I worded that wrong. I was asking how much the assembly that screws in the bolt costs.
 
After removing the firing pin group from the bolt, Panda, Bat, Rem 700, etc.,you can easily test the spring strength using a bathroom scales and a tubular item like a fired 30/06 cartridge. If the spring tests about 21# or more you are good to go. From about 17-21# your firing consistency is marginal, depending on the primer. If your spring is less than 17# wow will have inconsistent ignition.

Magnum primers like AT LEAST 22#.

I use a rod that will go inside of the spring, and a set of calipers for the correct spring height in its relaxed and compressed heights.
I agree with Jim, also. I fought an ignition problem a few years back. Changed the spring and it shot like a new barrel.

I agree with Jerry, a spring is easily checked. I set mine all up at over 22lbs, not over 25.

But, as James K said, they are easy to change with the proper tool. Better safe than sorry.

A number of years ago, a good friend bought a brand new action and built a Rifle on it. The thing was slick as grease, and amazingly smooth to open and close.

You could not make two bullets touch with it.

We took it to my shop, I offset drilled the trigger hanger and bushed it do the firing pin would have at least .220 travel. (This particular brand of Action was known for having only about .150 travel). I then made a spacer for the spring to get it up over 22 lbs.

Yes, the bolt lift was firmer. And you could feel the heavier spring pressure as you closed it. But the Rifle started shooting dots.
 
Couple of questions

What is the spring weight for a new spring for my Panda?
I ordered a mainspring changing tool from Sinclair to solve this problem.
What pins etc. might I need to replace/order that holds the firing pin assembly together?
The Sinclair you tube video shows the tool but does not show the complete disassembly.

I think the springs are 22lbs mine was on the original spring and I just took a small allen key and pushed my cocking piece cross pin out with hand pressure when I ordered my new one I asked kelblys if the cross pin sliding out easy was ok and to reuse it and they said yes.
