Hi Steve ,
I own both , a TX200 Hc in .22 and a Pro sport in .177 .
Both of these rifles are about 4 yrs old so I assume they are the latest incarnation .
I like both rifles , the Pro sport being one of the best rifles I have seen , however I get on best with the TX200 , it may be Me , but I find the Pro sport more hold sensitive , I would like to try a Pro sport in .22 to see if there is any difference 😀 but as others have said , they get different results with different rifles .
Slight thread drift ( I don’t hunt ) but My go to target springer is an HW80 in .22 very accurate and pellet on pellet and totally standard .
What I would say Steve is try a TX200 and see how You get on .
Kind regards
Paul
