"yenniedn"I have a .25 Vulcan and although I've not owned/shot a Wildcat, I have owned a number of other FX rifles including an Impact currently. Based on your request, I'd recommend the Vulcan. I looked at both of these rifles when researching my last bullpup purchase and pretty quickly ruled out the Wildcat in favor of the Vulcan. Granted at that time it was based entirely on reading feedback of others on this and other forums but there was a lot more people thoroughly happy with their Vulcan compared to the Wildcat. There seemed to be more nagging issues and build quality concerns with the Wildcat - whereas the main complaint about the Vulcan was focused around reducing the hammer spring noise (which has since been resolved).
Once I took possession of my .25 Vulcan, it almost immediately became my new favorite - displacing the longtime champ in the Edgun and persisting after the later acquisitions of several Colibri Hummingbirds and the FX Impact. I can't empirically say that the Vulcan is the most accurate of all my rifles because I shoot off of a front bag or bipod and there are too many factors I can't control (me, the wind, etc.) that affect accuracy; I'd say that if clamped down and shot indoors with no wind, etc. that all my rifles would do one hole groups at 30-50yds easily. What I can say is that the Vulcan is the rifle I'm most consistently accurate with because it's more ergonomic and easier (and more fun) to shoot so it's the one I always pick up when I HAVE to that rare squirrel that pops up in my yard. It's the shortest rifle I have at 26" and packs an accurate and consistent punch (the Wildcat in .25 would be 9" longer). It's easy to cock with the forward bolt that can be moved to either side of the rifle.
Lastly, the Vulcan is very well built and just feels solid when you hold it. I read too many complaints about QC issues with the Wildcat's cocking lever, mags, and other stuff and that's why I crossed it off my list pretty early on.
