Called Vudoo on Monday and talked to Greg Roman and we verified that I was setting the stroke of the firing pin correctly. Since I was still experiencing some light strikes (appx 6 out of 100) he speculated the firing pin spring had fatigued slightly and a couple of other details prompted him to send me all the internals for the bolt.I'll try to keep this to a short book length. I have a gen 2 Vudoo for about 3 years now and approximately 10k rounds thru. I decided to disassemble the bolt for proactive cleaning. Did not take a picture of firing pin set, didn't think I needed to I just followed Vudoo's YouTube video.
After reassembly according to video, rifle would not fire period.
Upon searching this forum I see there is a little more to setting the stroke of the FP than the video described. But I don't see a set method for this.
Right now I am getting approximately 5 light strikes per 100. Before the cleaning light strikes were NEVER an occurrence with this rifle.
Currently the FP is adjusted so that in the tripped condition the shoulder of the pin just meets the shoulder of the pocket in the nose housing.
Is there a definitive way to set the FP stroke? Some measurement/spacing that will get reliable ignition back.

Coincidentally I had just received a brick of the Lapua "Long Range" ammo and was testing it last weekend with the old set-up. With weak spring ES 29,S-D 8.
Tonight with new components ES 20, S-D 4.5.
In hindsight, considering some things that have happened to me in matches in the past maybe 8 months my ignition consistency was fading even before the actual light strikes appeared.
So, hats off to Vudoo for their stellar CS and hopefully this gets the rifle squared away for this years matches.
