With the bow, good conditions and enough light, I have no problem with a 40 yard shot and that's my limit. I practice it alot.
With a gun, I shoot about 500 rounds a year thru my 7mm mag and reload my own shells. I have no problem with 300 yard shots. I practice at 400 but have never had the opportunity to take a deer at that range. I've seen them at that range, but it was either windy or I wasn't sure of the distance so I haven't taken that 400 yard shot. I have a laser range finder now and there is one power line I hunt that gives me a possiblity of a 430 yard shot. If that opportunity comes and the conditions are right, I have no problem trying it.
