[QUOTE="BriKW, post: 1297985, member: 71363"] Finally got around to shooting my custom 280AI built by Eddie Fosnaugh, and I'm pleased to say that this rifle is accurate as hell. Eddie builds one heck of a rifle. [URL=http://s1151.photobucket.com/user/BriKW/media/Mobile%20Uploads/11032.jpeg.html][IMG]http://i1151.photobucket.com/albums/o626/BriKW/Mobile%20Uploads/11032.jpeg[/IMG][/URL] I'm working up a load using RL26 and the Nosler 150gn ABLR. I'm using Nosler Brass, and Fed 210 primers. COAL set to 3.340 Starting load was 58.5gn of RL26 with a muzzle velocity 2790 fps. Group size was 1.000 even steven. Next load was 59.0gn of RL26 with a muzzle velocity of 2874 fps. Group size shrank to .490 getting better. [URL=http://s1151.photobucket.com/user/BriKW/media/Mobile%20Uploads/20170325_133446.jpg.html][IMG]http://i1151.photobucket.com/albums/o626/BriKW/Mobile%20Uploads/20170325_133446.jpg[/IMG][/URL] Next two groups I had called fliers because I was getting careless with the way I was preloading the bipod. Muzzle hopped on me causing one shot to go vertical. But I was still under an inch on both groups. 59.5gn of RL26 had a muzzle velocity of 2910 and a group size of .742, and 60.0gn had a muzzle velocity of 2942 with a group size of .980 Once I corrected my hold and started paying more attention to the way I was preloading the bipod, I shot my best group of the day. 60.5gn RL26 muzzle velocity of 3013 fps. Group size of .145 I think I found my hunting load. Development over. [URL=http://s1151.photobucket.com/user/BriKW/media/Mobile%20Uploads/20170325_141949.jpg.html][IMG]http://i1151.photobucket.com/albums/o626/BriKW/Mobile%20Uploads/20170325_141949.jpg[/IMG][/URL] The last group of the day open back to .372. It was 61gn RL26 with a velocity of 3043 fps. I think I will load 10 rounds of the 60.5gn of RL26 to confirm it's my best load, and possibly try 62gns. If accuracy remains stable, perhaps I can fiddle with the seating depth and tune it in more, if not I'm quiet happy being at 3013 fps. Eddie Fosnaugh isn't only one heck of a coater, but he can build one hell of an accurate rifle as well. Not bad for the first day out. [/QUOTE]
