My own Weatherby Vanguard is chambered for the 300 Weatherby Magnum cartridge. It is a very fine rifle, it's beautiful to look at, it feels very confident in the hands, and is as accurate as any hunting rifle ever needs to be.
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.
