If you aim to shoot 5 GR - and put the first 3 in the same hole, then shooting the other two won’t really prove anything ? But not shooting them - takes away that pressure / anomaly - which is the shooter. ?
I’ve been load testing with friends - they’ll have 6 x 3 or 6 x 5 loads ready for testing, the very first 3 shots they shoot prints a tiny clover leaf...they are done. They will pull the rest of the bullets back at home - they have accomplished what they set out to do...
