So the rainy, windy weather finally broke and I got my first chance to take my XL .270 out to the range for some load development. started with 140 ballistic tips and 4831sc; first groups with starting loads were nothing special but as I got closer to max they started to improve, still nothing special tho so i decided to switch to CCI magnum primers and got this beauty with 57.4 grains for 2955 fps average. group measures .340 center to center...off to the gun store to pick up some more ballistic tips for further tuning this afternoon. gun is straight out of the box except for fire lapping which by the way made it a breeze to clean also; 4 patches with bore tech, no brushing and i get a clean white patch on #5.
