Sounds to me like 3 scopes or possibly 2. In order to do all that with one scope will require a compromise somewhere in your anticipated shooting repertoire. To do the hunting you have mentioned (coyotes, javelina) you might want a scope with a low enough setting for a quick or running shot. I personally think between 2 and 4. The only S III that fits here is the 3.5x10. This power range would allow you to easily hunt and shoot larger game out to 600 or more, but it is clearly not optimum for you longer range endeavors like target at 1000 ( although this can be done) but you will want more magnification. The scope in the Sightron line that fits here is the 6x24 which will serve nicely for the 1000 and the varmint but is a little high for the running or snap shots. Too bad they don't have a 4x16,,,that would be a decent compromise. So if you are really going to do all those things with one scope try and figure out which you will do most and make the compromise on the other shooting which you will do least...Good luck 30-338
