Partition 25 Caliber 100gr Bullet (50ct)

Every Partition bullet in the Nosler line delivers optimum length, weight and ogive design for maximum in-flight and terminal performance.
Minimum Velocity: 1800 fps
Maximum Velocity: Unlimited

1. Nosler Engineering

Nosler's special lead-alloy, dual-core provides superior mushrooming characteristics at virtually all impact velocities.

2. Fully Tapered Copper-Alloy Jacket

Ruptures instantly at the thin jacket mouth, yet the gradual thickening along the bullet's axis controls expansion and curls the jacket uniformly outward at high and low velocities.

3. Nosler's Integral Partition

Supports the expanded mushroom and retains the rear lead-alloy core. The enclosed rear core retains more than two-thirds of the original bullet weight for deep penetration.

4. Dual-Core Construction

Every Partition® bullet in the Nosler® line delivers optimum length, weight, and ogive design for maximum in-flight and terminal performance.

5. Special Crimp Locks

Adds strength to resist deformation under the pressure of heavy magnums.

  • Ol' Single Shot
    Review by Bob T / (Posted on 11/16/2016)
    I agree with Bret N above, one well placed Nosler partition in my 250-3000 is all that's needed on whitetail deer. And since Bret N needs only one shot, I would be willing to take all those pesky leftover cartridges he has left after his last hunt, as I have yet to fire a .257 Roberts...
    Now I only have to find a .257 Roberts rifle that I can borrow?;)

    I use the 100 grain Partition in an old Ruger #1 .257 Roberts @ 3000 fps and have never in 28 years fired a second shot on whitetail deer.
