Maybe you folks should start a new thread and title it "The ZEN Of Rimfire" ?
This thread has changed from ignition to shooting rhythm but there may still be some interest in ignition so I'll offer some thoughts:
The firing pin spring load, pin weight, and pin shape are all important and will affect ignition. However, these will stay relatively consistent and as long as a minimum striking force is established in the original action design there will probably be little change in ignition shot to shot. Where a change or inconsistency is most likely to occur will come from the rimfire case.
Ignition occurs because the U shaped rim is crushed or deformed. This crushes the primer. To what extent this U is deformed depends on the brass properties and the dimensions of the U. It wouldn't be unusual for any of the properties or dimensions to vary by 100% - even in the best ammo! It's this case variation, rather than the variation that might occur within the bolt that probably will cause an ignition problem.

I still maintain (although I have no "statistic" to back me up): 90% of ignition problems are case related rather than caused by some fault in the action.
How come, when you make claim to having some superior knowledge about something or other, you can never back it up. You always just refer back to what others have posted. Of course this always goes along with some stupid remark about me or what I post. You seem to think unless a shooter spends a lot of time at the bench, he can't possibly know anything about guns - or for that matter you don't seem to think he knows about ANYTHING! Now, this is all just an opinion I've formed by reading your posts. If I'm making an unfair judgment then I apologize, I sure don't want to hurt your feelings!
Now as to my experience: I've corrected ignition problems on several guns but not a Turbo or Hall. As I recall it's been only on Winchester, Anschutz, Remington, Stevens, Springfield, Ranger, Marlin. There may have been some others but these are the ones that come to memory. The corrections have consisted of changing entire spring/pin assembly, making a new pin, changing spring, lightening (or increasing weight) of the pin, reshaping the pin tip, changing headspace, and just freeing up motion of the parts by removing burrs, bits of primer, dirt, etc. This does not make me an expert and I'm sure it pales next to your experience . Also, not having worked on the super benchrest actions may disqualify me from making comments on ignition, but it's kinda fun - and I get to see your response, which is always good for a laugh!
