I'm on my second .257 Roberts and my favourite bullet is the 100gn Hornady SP. I haven't shot a deer with it, as I always seem to have another rifle with me when a buck appears, but I have shot well over 100 pigs with both rifles. A couple of years ago I switched to the 100gn Scirocco. They are not the most accurate bullet in my rifle but I did shoot a feral billy goat at 40 metres quartering towards me and the Scirocco penetrated over 20 inches before exiting. The billy just crumpled on the spot. I've switched to the 100gn Ballistic Tip this season and will see how they go. They have been a hard bullet in my .250 Savage (20" brl) so I hope an extra 300fps muzzle velocity opens them up a little quicker. I'll save the Sciroccos for my .25-06. I may just go back to the 100gn Hornady after playing around for a few years.
