All good tips, Mossydan. If there’s one thing that hunters and fishermen like more than partaking, it’s passing it on.
I would add that if you are driving, plan it carefully, get arial photos off of http://terraserver.microsoft.com or just a good topo map from the county conservation board and know exactly where everyone is going to be and where they are headed. Posters don’t move until the drivers come through. As a rule of thumb, the deer won’t go where you think they should – this is normal and don’t let it frustrate you too much.
If I’m stand hunting, I’ll wash my clothes in detergent, then run them through a cycle with baking soda to kill odors, as even odors from the detergents will spook deer. This is especially true in the winter when the air is crisp and snowcover has eliminated much of the normal smells of the fields and woods.
Your barrel will work, but for about $100 you can get a dedicated slug barrel with regular rifle sights. It’s a good investment to make. I also shoot a red-dot sight and would recommend it to anyone (although the holosights are pretty darned cool as well).
The one tip that makes for the most successful hunts and cannot be stressed enough: Talk to the landowners in the area. For the most part, if you’re in farm country, they’ll be happy to share info. Nobody spends as much time out there as these guys and they are our absolute #1 resource for information.
I’m sure I’ll think of more, good luck out there.
