I must be in the minority here because I disassemble all of my guns for cleaning. I am very fussy about getting everything clean. I do not have the kind of issues with losing my zero that some of you do. I guess my normal shots are between 30 and 100 yards, maybe if I shot at further distances I would have to do things different.
Everybody finds their own way of doing things and if it works for them that is great.
