Good Lord what range finder are you using that will give a range bounced off a 6" target at 500 yards? I want one.
500 yards ain't no joke. Anything past about 350 and you are entering a whole differnt world. Its great to practice that far, it can teach you a lot about the rifle you are shooting, and its pretty fun as well. If you are getting 1" groups from you T3 then I think you are more than ready to give it a go. Just let that barrel cool off. Study your ballistic chart.... and see how close it really is.
