Round Robin Method
What's your opinion on doing this for load development . Some info says use the same POI & colour your bullet tips just before your OGIVE. Thus in all the groups it will leave the colour on paper for each of say 3RDS , 4 etc . You then can see which load is giving you the group you like or to work with . The trick to show your colour if it hits a colour ring is to apply Isopropyl ( Alcohol ) to a cotton q-tip & turn it into the bullet hole . Colour will show up on q-tip . Has anyone tried this method .
