RE: Pellet gun maker, What pellet gun do you shoot?
For you guys quoting velocity, if you haven't chronographed your rifles, you're in for a shock. The vast majority won't get anywhere near the factory quoated velocities. Airgun companies tend to find the lightest pellet they can get for velocity testing. Of course some companies just tend to "estimate" high!
I've chrono'ed my rifles along with some friends' with hunting weight pellets and don't get anywhere near the factory quoated velocities.
