I have been to Rock Castle a few times when some good shooters were just practicing and it helped me a bunch,,at least now if I get lucky and get close enough on the first shot my spotter sees where it goes I can get on with the next shot,,
shooting on our home range at 1075 I can usually get within 1-1.5 minutes on the first shot and on calm days even make first round hits,,but I have a lot of ammo down range at that spot..
