1. yes to the good scope suggestion although i have no experience with what you already have.
2. scent control is debatable for deer, not as much for coyotes, and in many cases involves spraying yourself down with something. nothing REALLY hides your scent though. The best thing to do (other than washing clothes in something with no added scents) to control scent is determine the dominant wind direction, think about the direction that the game you seek may travel, and make sure the wind blows your scent away from any foreseeable approaching game. My coyote kills have been mostly luck with the stinking things showing up while I was hunting somewhere else.
3. if Georgia is like NC (terrain) then calling is going to be difficult. That's more of a western/open country thing. It's doable, i hear, but I haven't been able to do so successfully because of the lay of the land here. sound doesn't carry like it does out west.
4. Deer see blue very well, so if you are wearing jeans, try to cover your legs with something like an overhanging branch or blown down tree. It stands out to them because of the make up of their eyes (cones and rods and such, maybe a biologist will explain later)
5. I assume you meant fmjs for coyotes, because you should NOT be using FMJ's for deer. Frankly I don't think you should use FMJ's for either. While it may (key word MAY) work for coyotes, it won't work for deer, and each load shoots differently from each rifle, so if a rifle is pulling double duty and you are changing ammo, that means you will have to re-zero every time you decide to go with an actual deer round. OR, it will mean you go out coyote hunting, see a deer, and have to watch it walk off because your rifle/scope are set up for the FMJ's. I suggest you just find a good deer round that your rifle likes and use it for the dogs as well. If you don't want to use a deer round for coyotes for some reason (everyone is different after all) then just take the shot gun and the rifle, that way you can bust the coyotes with some buck shot.
6. (unsolicited add-on) if you are only hunting cow pastures (you didn't say that, but you did mention cattle) then i suggest hunting the woods AROUND said pasture. When hunting pressure heats up you won't see many deer or coyotes in open areas during shooting light. It happens but not as often as many people hope.
7. A final comment to you personally: Thank you for asking questions and doing so humbly. Keep that attitude up and you won't catch hell from people as often as you have in previous posts. Humility is a wonderful attribute. We all get cocky from time to time and if I were to see my 14 year old self walking around i would probably beat the heck out of him because he was as arrogant as one can be, but you asked some good questions this time and seem willing to learn. Good job!
1-6 YMMV 7. well that's just absolutely true.
