I've got the 16 in contender barrel,and enjoy it, my son took his second moose with it when he was 15,a light load under a 300 gr hard cast, broke ribs on both sides and the offside shoulder, we didn't recover the bullet as it exited.Also have a rifle barrel for the Encore and took this springs black bear with it ,a 350 gr jhp full house load.Any hot load {Ruger #1] is quite a handful even in the rifle it's not much fun.No matter what load your using it should be more than you need for any deer.Just remember no matter what load your using beyond 100 yds the drop becomes a factor very quickly.
