My favorite 257 Roberts with 100 gr. core-Lokt handloads killed a truckload of Texas whitetails and feral hogs over the last 40 years, it was so accurate in that rifle that I never tried another bullet brand or weight. I recovered a couple and they mushroomed just fine and held onto the core. At 3000 fps, maybe that was their sweet spot. I never knew that Hornady made them, but I used to buy them by the pound in the 80/90's at Houston gun shows, the vendor had 50 cal ammo cans full of loose core-lok bullets in about every caliber and weight they made and they were cheap!
