Ackley, the modified 257 Roberts was likely the best improved round compared with the couple dozen or so factory cartridges he’d experimented with Ackley’s signature case modifications included reducing the body taper and increasing the shoulder angle—both significantly! However, an even more important feature of the typical Ackley Improved (AI) wildcat is that he maintained the shoulder headspace datum of the parent factory round. That allows you to safely fire factory cartridges in the modified chamber. It also means you can easily fireform .257 Roberts factory brass or loaded rounds to achieve the .257 AI case shape, so you don’t need expensive forming dies or go through extensive case-forming steps. Ned H. Roberts was one of several handloaders who experimented with wildcat cartridges in the 1920s and ’30s. He chose the 7x57mm Mauser case to modify and, reportedly, tested myriad configurations before settling on the “perfect” .25-caliber varmint and deer cartridge. Early articles by Townsend Whelen and Jack O’Connor proclaimed the virtues of the .257 Roberts in the hunting fields. Many hunting and reloading articles fondly referred to Ned Roberts’s wildcat as the “.257 Bob.” When Remington decided to adopt it as a factory cartridge in 1934, the company made a few minor dimensional changes to preclude firing factory ammo in rifles chambered for the wildcat round. Remington paid homage to the inventor by naming the new factory round the .257 Remington Roberts. The Remington part of the moniker was eventually dropped. The current SAAMI spec for the .257 Roberts Maximum Average Pressure (MAP) is 54,000 psi. Winchester introduced a +P version with a MAP of 58,000 psi in the mid-1980s. That’s still less than the typical 60,000 to 65,000 psi of comparable modern rifle cartridges.
