Frequently Asked Questions
Buy .257 ROBERTS +P Ammo for Sale
What is the pressure on a 257 Roberts +P?
.257 Roberts +P operates at 58,000 psi according to SAAMI specifications, compared to 54,000 psi for standard .257 Roberts. Older or vintage actions may warrant caution with +P loads.
What is a 257 Roberts equivalent to?
The .257 Roberts sits between the .250-3000 Savage and the .25-06 Remington in performance, pushing 117- to 120-grain bullets to 2,700 fps or more. It is roughly equivalent to a mild .25-06 load and is well-suited for deer-sized game at moderate ranges.
What is 257 Roberts good for?
.257 Roberts excels at hunting deer and similar-sized game at moderate ranges with mild recoil. Lighter loads work well for varmints, while heavier 117-120 grain bullets are adequate for elk and caribou. It is accurate and versatile, suitable for both hunting and range shooting.
Is 257 Roberts ammo still made?
Yes, .257 Roberts remains in production. Hornady and Remington both manufacture factory loads, including Remington's Core-Lokt line. Availability is limited compared to mainstream calibers, but ammunition is still produced and sold through retailers. Typical pricing runs around $60 per box.
Is the 257 Roberts actually improved?
The .257 Roberts Improved uses a steeper shoulder angle (typically 40 degrees) to increase case capacity over the standard cartridge. It accepts standard .257 Roberts ammunition, which fire-forms to the improved chamber. Velocity gains are modest—realistically around 100 fps—making it a refinement rather than a dramatic upgrade.
What is the best bullet for 257 Roberts?
Best bullet depends on your purpose. For deer and larger game, 100-120 grain bullets like the Nosler Partition or Barnes TSX work well. For varmints, 75-87 grain options like Sierra hollow points or Nosler Ballistic Tips are effective. Match bullet weight to your intended game.
