After shooting at the Paul James British recoiling championships last week there were mainly TX200's, HW97's and more than a few Prosports including mine. There were a few HW break barrels and Walther LGU's . I would say on balance TX 200 HW97 and Prosports were the main guns in that order.
The FT shooters were mainly using Big Nikko's and 8x32 Bushnells from what I could see. The HFT shooters as usual were using all sorts of 10x mag and 3x9x40 stuff.
