Thread: How far in is enough?

The general rule of thumb is the bullet should be seated at least it's diameter into the neck, i.e. .22 for 22 cal, .308 for 30 cal.
But I have had loads with a lot less length seated that have shot very well.

To add to that, I'd be comfortable seating a 22 to .15, that's about two-thirds of the diameter so not really shallow.
