I bought this gun a while ago. I finally dug it out and hit the range with it's 30 br barrel installed. I haven't even measured the twist yet. A friend called me Sunday and said he was off on Monday and suggested a range trip. I barely had time to load some test rounds Sunday evening. I bought some 115 grain "custom" bullets for this gun and segregated them by weight into 3 batches. I shot some of the lightest bullets first. Set at touching the lands, they shot fairly well over H4198 in the primed brass that came with the gun. Primer unknown. Best group was at 35 grains, just where the previous owner said it would. The flier on 34.4 was me. I sneezed and touched the trigger. I adjusted the scope after the first group. I also wanted to try some "really cheap" 125 SMK in the gun to see how they would do. Also set to touch, I got some strange results. I half expected some key holing but the 33.5 grain group has me scratching my head. Sweet spot or fluke?
