The new rifle owner looked with disbelief at the holes in the target – a three-shot group larger than three inches! There had to be a major problem. His new rifle was chosen with care, as were the rest of the components, it was supposed to be accurate right out of the box.
If he was shooting factory ammunition it was time to change to another brand or projectile type. In simple terms the rifle could not achieve its true level of accuracy with that particular cartridge or projectile combination. If on the other hand he was shooting handloads and this load was the lowest in charge weight, the results on paper might not be unusual. He would probably notice that the next highest charge weight actually produced a smaller group. This is normal. Often the subsequent groups will continue to reduce in size, then start to open up again. It is also possible that the maximum load will produce the best groups.
