FX Impact, .177, 600mm barrel, Heavy Varmint class, in-door 50' BR match at Phoenix Airgun-Rio Salado. The FX Impact I. .177 does not have a good competition reputation. I had tried several times to compete with my FX, previously shooting a Wolverine. The FX was a dog. Installed a BC Tension System and was able to shoot a 104.1 card - Orion scoring system. Really a big improvement!
