I'll be hunting deer and bear in the ozark mountains. Range in the 50 yard area. My drilling is a like new one 23 years old. It's chambered for 12 ga 2 3/4 chamber. The full choke barrel throws remington slugs at the proper elevation but 6 inches to the right. From the modified barrel it throws the same slug at the proper windage but 12 inches low at 50 yards. I'm not really happy with this. At this rate I can use slugs in the full choke barrel and maybe buckshot in the modified. However, it would be great to have something that would approach similar poi from either barrel. Any ideas? Is it even possible to get what I want?
