If you don't want to go that route, you can call the G&F district headquarters that you want to hunt in and ask them for a list of ranch owners that would allow you to hunt on their property for a trespass fee. They will send you a list of names of the people that own the ranch, the ranch name...
I shoot 2 50gr. Pyrodex pellets out of my Knight and it is very accurate. I tried shooting 3 pellets and I could not get the gun to group very well with 250 gr. barnes bullet.
