Well I have sorted the choke and yildiz gun fit! Found out about Browning Game One Light, the only reason I tried a Yildiz 20 was the weight, compared to my original 30" Browning at 7 1/2 lbs
which was aggravating my spine! Shame I did not notice the Game Light before, Any way I got there! Like my original Game one this suits my build great! Just so much more comfortable on my spine, Yippee
