Better than the xbox one, but I'd stick with more established extensions. I have 4 .co names and none get any traffic worth mentioning - and two of them are Spanish...one of those is a popular product in English too.
The only .co names that are selling (and not in great numbers) are ultra-premium, very high search volume generics - and the buyers are finding the sellers.
Shame because I like clay shooting too - still the youngest Brit to shoot 100 straight at Olympic Trap nearly 25 years after I did it.
That said...I reckon you could get £150 for it given a day pushing it - maybe upto £500. My strategy with this would be email potential buyers (shooting grounds / hospitality companies / clay manufacturers etc) once, and stick it on Sedo etc.
