I think buried away in my waffles in print, is at least one mention of the FT GP series being lead by an hw77 and i think a custom shop on top... 2nd hand price perhaps £500-600 tops.
Nick Murphy was only 1-2 shots behind me after a 100 targets in Euskadi last weekend with his Tx200.
I think Pete has also mentioned that the HFT Worlds was won with an S400 this year, and one came 3rd in the FT a few years back.
Everyone likes their gear. Even hunters now elect for PCP over springers, so it's not just a target sport thing.
You still need someone to drive the thing. Pretty guns look nice, and custom guns reflect the enthusiasm of the owner, but you can't buy talent, skill or hard work, else I would have already done so
