I just got my PAC nor barrel. 1.250 strait 28 long 1.8 twist. I would like to try and get the 55's or 57 vlds from unmussig to shoot. I have 300 of unmussig bullets i will try them first. Has anyone tried just the 204 ruger AI with this set up. I would like to know what powder and bullet speed, just to get me in the ball park. The reamer is a pacific tool and gauge, Dave wanted to use .100 free bore. Any results would be great tell me what works and don't. The plan is to shoot p-dogs at 500 to 700 yards, and do some varmint shooting around the area. Its on a edge stock nightforce scope gun weights 20 pounds. Thanks for any in put on this project. Andy
