When I find something the Ultra Mag will not shoot well.. I will post that. So far almost anything I have thrown at it, this rifle has handled and handled well. I think starting at 25 yards is a good idea. It will help you build conifidence in the rifle and you do not have to worry about distance spreads. They can fool people sometimes. They think a bullet is not grouping well, when really because of the distance they are having flyers or just a plain old bad day. I sure have had enough of them.

Good luck with your rifle and be sure and let us know how it shoots and handles...
