A little more on shooting.
Check your gun when you arrive at your destination. Do a little research ahead of time and find a place to set up a simple target and shoot over a pack or the truck hood to make sure your scope is on. Be careful to find somewhere that it won't bother anyone and is safe.
If you plan to take an optics tripod see if you can get a shooting rest for it also, or practice using your hand on the top of it to make a rest. Practice this sitting and kneeling with your elbow rested inside your knee. If you have a pack with a solid frame or stout stays, practice shooting sitting with the gun rested on the top of the pack set upright in front of you. If you plan to use shooting sticks or the tripod, practice setting them up quickly until you can do it without looking at them and taking your eyes off the buck. I do this in front of the TV while watching hunting shows with an unloaded rifle. Practice prone resting over the pack also.
Another thing that can be done at home with an unloaded rifle is picking a spot across the room and bringing the gun to your shoulder repeatedly until the crosshairs are always aligned with your eye when the gun hits your shoulder. I have shot a lot of 4.5-14x Leupold scopes with a 19.9ft field of view at 100yds on my rifles, it can be a little tight on close fast shots. Practice helps.
I'm lucky to live where I can have a simple 100yd range in my yard and shoot further within a couple miles. I shoot a lot year round and it has paid off big over the years. Its a skill that needs regular practice to keep at peak level. I notice that my friend I hunt with is slower to get on target now since he lives and works in town than he used to be when we were constantly shooting together. He is still a good shot and accurate, just not quite as fast on target without the constant practice.
Also remember that even the best shots in the world miss. It's easy to say, hard to do but let the misses go and not ruin your concentration or optimism. Being dejected and replaying a miss over and over takes concentration away from the remainder of the hunt. Be careful in shot selection too as was mentioned earlier, a miss is much better than losing a poorly hit animal.
There are so many variables in hunting that are beyond my control, they are part of what makes it so much fun. Shooting is one aspect of hunting we do have control over.
