I’m not an overly-technical person, so I had my heart firmly in my mouth when I decided to follow Jim Tyler’s advice and apply his recommended ‘simple tune’ to my Walther LGV. I read and re-read Jim’s article from your July issue, and finally decided to go for it, fitting the Air Arms Mk 3 TX200 mainspring, plus a new, slightly larger, spring guide. I’ve left the transfer port as standard, for now, but after some experimentation with pre-load washers, my LGV is producing 11.2 ft.lbs. with .177 Air Arms Field pellets, and it’s never felt smoother to shoot. I can’t tell you how happy I am about this, but please pass on my thanks to that genius, Jim Tyler, and thanks to you, too, for producing such an informative magazine. RON KING
The gentleman genius that is Jim Tyler knows a good tune when he finds one.
