Thanks for all the good feedback everyone. It seems like a toss up. I will try 50gr and 80gr loads and see if she can tell the difference. She has hunted with a bow for 10 years and just got into gun hunting the past 2 years. I wouldn't have this problem if they would allow the use of a .410 or even 28ga. for deer. Heck thats what I would be shooting.
The deer we are talking about range from yearlings weighing in at 100 lbs. dressed and mature bucks at 200lbs. so it varies on what walks in front of her.
Thanks again!
