As above really and hold sensitivity can also vary hugely between different rifles with the old springer shooting business being a dark art and i found out by going the long route that when it comes down to it there’s no substitute for practice, i tried 5 different top of the range rifles which were stock/tuned by various people and always hit a ceiling of around 49/60 on the course with my biggest problem being an inconsistent follow through of the shot, I really enjoyed my hft days though and very very sadly my local hft shoot which was Quarry Hunters is now closed…
