Thread: 3 vs 5 shot groups

After I use factory or a generic book load to get on paper for a for brand new loads , eg new rifle, new caliber powder combo etc I also load 4 shots incase I can call one a flyer, however if after three and I can tell it's crap I don't bother with the last one. Take it home and pull it.
When satisfied and validating at 100m I load 8 and fire two distinct groups.
Might not be conventional but it's done me ok.
