I just started reloading and I worked up an load using Sierra 63 grain varminter,and 35.7 grains of h414. I am getting 1/2 MOA groups at 100 yards but I am getting a lot of flyers. I get about 1 flyer in every 5 shot group. Most times I get 4 shots touching and 1 shot about 1 inch high. Could this be caused by deformation of the soft point tip of the bullet or is it more likely neck tension or differences in the powder charge? The rifle is a savage 12LPV.
