No trouble, as such. I was in conversation over the weekend with a wise one, Not Holly, and was discussing EV mods to get a better consistancy of shot.
Looking over the GP's last year, there are many stock mods, but little is mentioned about Reg tweeks, sweet spots on the Transfer port, Favoured hammer Spring tensions etc etc.
I wouldn't want to become obsessed with chrono readings, but how else do you measure mechaincal consistancy? Trophies on the Mantle piece point to a whole different level of shooting consistancy, which is where we all want to be.
