I traded a brand new S510 for an FX Verninator with my buddy Lee Chiu, he says he already misses it, sorry but it will be staying with me for at least a little while! I have only been able to shoot it at shorter distances because I have serious issues with my legs, even so you get an idea of how well a gun shoots when you shoot it without a proper rest and get one hole groups at 20 yards. The S510 was very accurate at 50 yards and I hope to be well enough to test the FX out to 50 yards very soon, I will then post an update on its accuracy. But so far there is nothing about the gun that I don't like, it is a really sweet gun, Neil.
