I've heard many times, Hornady's 45-70 brass is shorter than other brands. But I thought that was specific to that caliber. I seem to recall having some Hornady branded 500 S&W Mag, I don't recall them being short? or maybe I didn't notice? It's rare I come across Hornady brass in my range brass pickups or used brass purchases. This weekend, I am cleaning up and sorting some 357Mag brass from a recent purchase from a fellow castboolits member (this is no critique on the deal, I am happy with the deal). I sort and store all my brass by HS, and load by batch (per same HS). As I am storing all this 357Mag brass, there is some Hornady's in there, I find a baggie in my stash that had some 357Mag Hornady's in it, and I had marked that baggie "short cases". I measure the cases I had just sorted, and sure enough all the Hornady's are short.
The Question are:
Are all Hornady's brass short?
Or just certain calibers?
and why do they do this?
