Stolle Panda firing pin spring.

Does anyone have any data on the firing pin spring force/ load for a 1982 Panda. I tried measuring it but got technically confused. Ive substituted a 28# Wolffe Rem 700 spring which does seem to register ~28#. The original spring seems to be abt 20#,
 
The spring you have will do just fine. The differences youre seeing is a new spring and worn out one. 28# may be a tad on the high side but is better than 20
 
The Duo's David Tubb is offering sound interesting. They feature two counter wound springs that prevent bolt jump. I just finished installing 3 sets and as soon as this snow melts, I am anxious to try them out. About $20/set.

They are supposed to hold set weight forever!

I have a set on my Viper, and ordered two sets for my friend's Pandas. They measure 25# cocked, and the top half of the bolt lift is easier than when a one piece spring is used. I heard of them (it?) from a post that Speedy made on Facebook. The springs are wound in opposite directions so that the normal sliding of their ends as they are compressed, cancels out, rather than the ends of a single spring turning slightly against the surfaces that they are compressed against. Before I looked into this setup, I had not been aware that this end of spring "scooting" as a coil spring is compressed even takes place. Tubb's springs go on the firing pen end to end, abutting each other in the middle of the pin shank. Personally, I think that they are a great idea, and that any action that can take a standard Remington spring (long or short) or Winchester, would benefit from the change. Besides the reduction of bolt lift, there seems to be a reduction in vibration during the firing cycle (dry firing).
 
Which Spring?

Which spring did you order for a Viper?

Yesterday I took one of the Pandas that has the new Duo spring out for a test. Granted it is only one test but 9 groups of 9 different loads of my standard matrix that I already had data on. It may have been me just wanting to get out and shoot but the 9 groups were all better than when I had shot them in the rifle with a conventional one-piece spring.

So???
