Case failure
The (blurry) picture is of a 220 swift WW Super Casing with a vertical failure, at the beginning of the failure there appears to be a pin hole where it burned through. This was a hand load with 41gr Hodgdon H380, Nosler 55gr Bullet and a COL of 2.72
Hodgdon load data does not show any data for a 55gr. Nosler, the only 55gr. bullet they list is a Hornaday 55gr. SP with a min/max powder charge of 39-42.5 grain with a COL of 2.68.
This isn't my load, so assuming everything is as stated what would cause this type of failure?
