1-10" is more common to handle the more streamline heavier weights. While I haven't run a program on the issue, I would say 1-12" is more appropriate. That said, I also have been a proponenet, of when in doubt a tad faster is better than a tad slower. If you are over stabilized slightly, you may find to things. At shorter range, it takes time for the bullet to "sleep", therefore you may not see it's real accuracy potenial untill 100-200 yds. Then again at extreme range their are other problems, But these range are way out there beyond the norm of hunting.
Personally, in a rifle barrel, I would go with the 12" twist if I had no plans of shooting anything over a 200 gr. VLD.
Try to put your tree stand in a tree with plenty of background cover, keep the prevailing winds for that time of the year to your face, and take care of those pesky squeaks and creaks your stand may have developed while sitting in the shed. A good treestand lube can be made by heating petroleum jelly until it reaches a liquid form. Some hunters have reported success by including a cover scent in this mixture before applying it to their stands.
