Case length? I've found an issue with Hornady dies - not so much cases - with cases getting stuck in the dies. The Hornady dies produce very concentric ammo but take some massive force to operate on the press. Way more than any other brand of dies I've used...
With the cases I'm not sure why you would be having an issue with just that brand of cases - are they the same number of firings, same length and same shoulder length etc etc? Worth while doing a couple of basic tests to check the neck hardness, crush with pliers and then cut from the mouth to the shoulder with sidecutters - that will give you a comparison between a Hornady case and one of the others you aren't having the issue with as a 'hand-draulic' measurement value. The other is an inspection of the case rims, and a check on how the cases fit the shellholder. Might well be that you need a different shellholder for the Hornady cases, have struck this with some Lapua cases and then tearing rims off Norma in the next cycle as the Norma cases didn't fit the same shellholder the Lapua cases did.
