All of my .257 Roberts' rifles have had long actions because that's how they came, not because that's how I wanted them. The Ruger Hawkeye has quite a short throat so the extra magazine room is wasted as I can't seat the bullet out any longer than the lands allow with the bullet seated 30 thou off. Interestingly, a .257 Roberts cartridge will fit easily into my Ruger .308 magazine box, indicating that the Roberts would work fine in a short action. I usually stick to 100gn bullets in the Roberts and have larger .25 cals to shoot heavier bullets. The 100gn Hornady and Ballistic Tips for all round use and the 100gn Scirocco if I want to beef the load up a bit. The 100gn Partition was a good bullet also, but I've run out and have enough Sciroccos to last me years.
