Hey guys i've got a question. i have a savage .243 that i sighted in at 100 yards. we'll i've been seeing this big buck on my trail camera and the only way i can get a chance at him is to hunt from my tree stand witch would put me shooting at 20 yards. Do you think i can make this shot without re sighting my gun? i really don't wont to make any noise in this hunting area right now.
