I own a Winchester Model 70 Cabela's Anniversary .257 Roberts. I talked to a number ho bought the same rifle. I used to reload the cases. But every cartridge I tried shot incredibly tight groups. I use the 117 grain Hornady Superformance round mostly but Federal, Windhester, Remington, and in several different weights all were very accurate.
I will say the .257 Roberts is about the best round I know of. I knew Jack O'Connor and his experience was extraordinary, he felt the .257 Roberts was almost perfect for most hunting. Brown Bears and Cape Buffalo are never going to be on my hunting list.
