Deep Dive

Overview

The Underwood Extreme Terminal Performance (XTP) 357 Hollow Point Ammunition is crafted for those requiring a powerful round for medium game hunting and personal defense.

Common Questions and FAQs

  • How is this ammunition packaged, and are bulk options available?
    This Underwood 357 magnum hollow point ammunition is sold in 20-round boxes and 200-round cases. Bulk purchases are eligible for free shipping, making it a cost-effective option.
  • Can this ammunition be used in aluminum or scandium-framed revolvers?
    It is not recommended due to the significant recoil that can affect the integrity of lighter-framed pistols.
  • What makes the nickel-plated brass casing beneficial?
    The nickel plating provides smoother feeding, better corrosion resistance, and ease of cleanup and reload after firing.
  • Is this ammo suitable for snub-nose revolvers?
    While usable, expect considerable recoil which may require adjusting to ensure comfort and accuracy.
  • Does the ammunition have any lighting effects?
    Underwood utilizes flash-suppressed powder to prevent vision impairment during low-light firing.
  • Is it safe to reload these casings?
    Yes, they are reloadable, made with Boxer primers and designed for multiple cycles with quality retention.

The 'Round Up'

Perfect Fit for:

  • Medium game Hunting / Personal defense

Why It Stands Out:

Underwood Extreme Terminal Performance 357 Magnum ammunition is meticulously engineered for effective use in medium game hunting and personal defense scenarios. Offering impeccable stopping power, its Hornady XTP bullet ensures accuracy and deep penetration. Customers looking for control and power will appreciate the nickel-plated brass casing's benefits, such as enhanced feeding and corrosion resistance, particularly in steel-framed revolvers.

Not all that accurate in my single shot 16.5in barrel rifle. Best I could get from a lead sled was 3 MOA groups at 100y.
