Recocking and having second pop is not the misfire procedure on most of the ranges I shoot on including Bisley.
I wondered about that. I do wait for 30 seconds before recocking and trying again, if no luck then I wait another 30 secs and remove the round according to the misfire rules.
I don't like having to do it, hence my asking about getting the problem resolved.

The whole point of not refiring a second time is that if the primer has been struck the first time then the cup is weakened and could rupture causing gas blow back if it goes off the second time.
If it is ammunition related then sort the ammunition supply if it is firearm related then fix the firearm, personally I would not use the firearm again if it is the fault until it was fixed, one of our members just recently reported a bleeding thumb due to a pierced primer.
Such practices as you describe seem unsafe to me. If I was RCOing and saw you do that I would tell you to leave the range.
Click no bang is a misfire and should be treated and cleared as such.

Three things apply to myself
1. Initially I did carry out mis fire drills , only to inspect the round to not see any strike marks. But having this repeatedly then the law of probability of a 'mis fire' in the context that you consider is diminished.
2. Am using mine on private land not restrained by range rules
3. If this was from one of my bolt actions then I would not be cycling the bolt straight away, but as the hammer is external re cocking is possible without cycling the action.
Now, if you feel I am being irresponsible then that is fine, when at a range then I always abide by the governing rules. It's like driving on the road- you follow the law, but drive your car on your own land and that's entirely different.
As a newcomer to the sport having only been involved for the last 34 years, I can't say I have seen it all- but like to think I am responsible enough, but at the same time I respect other's right to an opinion.

Any suggestions for what needs furtling?
Have you replaced the main spring?

I replaced it with the lighter one from the StevesGunz kit, I did wonder if that might be the issue, although I did have the same problem before I put that down to the firing pin (now replaced) being too short. Guess it might be a sound idea to ask Steve about whether the lighter spring has caused this problem for others. Not a big job to put the old one back to test it.

Take the lighter one out and get a new, full power spring. It was far more likely that the original spring was the issue in the first place as opposed to a short firing pin.
Out of interest, did you measure the old pin against the new?

I would be interested as to how a thumb could fall in line of a discharge from a failed primer ? and perhaps now is the right time to mention shooting glasses ?

I suggest that you ask the member concerned as they might know best.
