One of these is not like the others...

I have done much worse myself, but not my handiwork. I think these are fireform loads. The loader decided to "crimp" the bullets without cannuler in them to capture brass flow. Typically for the single shot I simply treat rounds the same as for a bolt rifle, I let the correct neck tension hold the bullet. Also he must have used a very short case to set the dies. A longer case gets the guts crimped out, where as a shorter gets a lesser treatment. Note the case mouth deformation and shoulder buckle. Being fireform rounds these luckily chamber and blow out fine, only needing a uniform trim to suit. Far left illustrates a desired .280 GNR round.

No harm, just some fine points for collective training.
