20 rounds Remington® Premier® A-FrameTM Centerfire Ammo, PRICED RIGHT!

The most-reliable cross-membered bullet made today, Premier® A-Frame™ Centerfire Ammunition is virtually custom-made for situations where there can be no compromise in quality, reliability or performance.

Remington® loaded the dual-core A-Frame bullets, so that you can expect reliable expansion at long-range decreased velocities, but without the over-expansion at short-range high velocities. The combination of A-Frame construction and proprietary bonding process produces extremely uniform, controlled expansion to 2X caliber with nearly 100% weight retention.

All Premier A-Frame components receive multiple inspections: primers are pre-inspected five times for ignition reliability, each round is receiver-gauged, and case are nickel-plated for precision feeding and extraction. You simply can't buy a better factory-loaded medium to big-game ammo!

20 rounds Sellier & Bellot® Nosler Partition Hunting Ammo. Hard-hitting, maximum-penetrating hunting rounds, PRICED LOW!

Nosler Partition Rounds deliver the kind of accuracy, controlled expansion, and weight retention hunters around the world have relied on for years. The Rounds are built to withstand the violent impact of high velocity at close range, but still expand reliably at extreme range.

The Nosler Partition is a bullet with two lead cores separated by a solid metal partition. The thick jacket, tightly crimped to the rear core, ensures the bullet's mechanical integrity and delivers deep penetration. A thin front jacket promotes rapid and dramatic expansion. This proven technology assures the right combination of shock effect and maximum penetration. Brass-cased, boxer-primed, reloadable and non-corrosive.

Here's more on the "tech":
  • Projectile - Dual-core bullet construction provides the front-core dependable expansion, while the rear core remains intact to drive forward for deeper penetration.
  • Powder - Clean-burning propellants are matched to each load to deliver optimum velocity while ensuring consistent chamber pressures and downrange accuracy.
  • Casings - Reloadable brass cases manufactured to exacting dimensional tolerances for quality assurance. Reliable feeding, smooth functioning, corrosion resistance and produced to precise hardness.
  • Primer - Non-corrosive Magtech and Sellier & Bellot® primers are manufactured with sensitive priming mixture to ensure uniform and reliable powder ignition.
