I would advise you to use a rangefinder and find out what patterns to that range soon as you can and when you get to your stand range some trees. Try different guns or chokes depending on woods type. Thicker woods #1 open woods tighter pattern #1 or 00. 30-40 yds probably best range further not so good. I like the idea myself of more pellets is better if you can slow it down those dogs may catch it for you. Good dogs won't stop until they get the deer or someone catches them. 60 yards if too far sometimes looks a lot closer.
