Hi Greg, welcome to the forum, nice to have you with us.....
As for the Winchester or Blackhawk dilemma.... Well, it all depends on what you really want to do....but here are some things to think about....
the winchester is a "refurb"........ the Blackhawk isn't .....
the Blackhawk, being a clone of the RWS 34, is going to have a MUCH better stock trigger than the Winchester for sure..
The winchester is an 800 FPS rifle while the Blackhawk is a 1000 FPS rifles. Both those FPS figures are "advertised" of course and are not "real world" but the Blackhawk is going to shoot faster and more power.
The Blackhawk comes with a scope (not the best of course but usable)... the winchester does not.....
Last thing,,,, the Blackhawk will be much easier to get spare parts for if you ever need them or want them, springs,seals, etc,,, since it's a 34 clone.
I"m not trying to push you either way, just throwing some things out there to think about to help you make your decision....
Hope this helps.....
Will be looking forward to your future posts on the forum.....and again.... WELCOME :)
