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.

one on the left.

Shooting the ugly ones is how you get there

These were, admittedly, treated a little roughly. But as long as the neck is in the end of the chamber mouth as it should be the brass will expand to form a near perfect case. As Gary said running from .408" down to .284" is a pretty big feat. I used to go .375, .358, .338 or .308 then .284. The more steps the less deformation to iron out. You can go from .408 to .338 in one pass, but why risk folding a case? .375 then .338 is pretty smooth.

The main thing is to not crimp where you don't need it and don't over do it. When you do this is what it looks like. A rare example to view. Only a few in the box were like this. We are shooting them!

Looks like he...........

Cut the 2 on the right down with a plumbers copper pipe cutter, that wasn't tight on the pipe.

they haven't been cut down at all. The 280 GNR does

not need cutting down. But during the sizing down from 405 to .284 caliber the neck will sometimes stretch a bit more on one side than the other. Normally you would not trim it back to square until after the fireforming process. Those 2 cases have not been fireformed yet.
