Neck sizing vs full length

[Straightshooter1]

I saw a T-shirt that I interpreted as making fun of neck sizing at the F-class nationals last week. It was a picture of a target with impacts all over it in an open choke pattern with a caption "I NECK SIZE".

Yeah . . . a funny shirt. It suggests an accuracy issue with neck sizing, but actually the issue is really about extraction. A more appropriate picture then might be a large mallet striking the bolt handle to get it open.
