Update.........went out Fri. Spent 9 hrs in my blind. Got a nice doe at 5:30pm. Heart shot at about 50 yds. Fell over like she was hit by a truck, never went a foot! Went out Sat. morning got another doe, double lung shot. Same results, never went a foot! No heart hit this time........I must be slipping but not bad for a 75 yr old.
