.243 VihtaVuori Powder = Heavy Bullets

Still experimenting with 103’s. I am getting strange spread between 42-43 grains. Bullets go into the same hole but a 5-shot string will be 2” @100

1 bullet goes next bullet is 2” away and the rest go though the same holes in an alternating shots. Velocity and SD are great.
How far off the lands on those 103's
