You may be right. But, typically when your loads are doing this, a slight adjustment in bullet seat depth will solve the problem.

You start by examining the average of your groups shape. If there are 2 together and the 3rd shot out of the group, the OAL is too long for your rifle chamber and you need to seat the bullet deeper.

Seat deeper and repeat until the 3rd bullet comes into the group.

If the groups are large equilateral triangles, the OAL is too short so you do the opposite and seat out until the group shrinks.


Thanks for the remedial lesson. Now here's a recap since you weren't paying attention:

shots one and three land directly on top of each other. shot two is randomly elsewhere on the paper.

cleaning (with no other changes) stopped this occurring for a while. then it began again. seating depth never changed.

now do tell, how seating depth that never changes, somehow works part of the time but not the rest of the time, and it's shot number TWO, not three, that's errant?
