Welcome to BGH! Nice buck you got there. It appears that the heaviest buck on record was 500 lbs. from MN. What state did you shoot yours in? Not uncommon for big bucks around here to hit the 300 + lb. mark. Lot of crops to help that.
You would be right Red.... Just goes to show the complainers that the deer programs are working VERY WELL.... Reduced numbers are creating bigger and healthier deer... PROOF is in the pudding as they say... NICE BUCK!!!
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.
