I've owned a lot of 257 Roberts rifles, still have 11 of them, and while I like it, it has been primarily a reloader's cartridge for close to 50 years. When I was a kid, Winchester/Olin cataloged 3 bullet weights and styles of 257 Roberts factory ammo that made it a more flexible varmint and medium game cartridge. I have long followed the road less traveled when it comes to cartridges. While I think that the 257 Roberts is a nice little cartridge, looking at it with a critical eye, I see it as a more expensive and less practical way to get the same approximate level of performance as the common as dirt .243 Winchester.
