SPEER 45-70 (.458) 300gr BULLET HP 50/bx

The bullet that delivers a TRIPLE IMPACT – One when it first strikes game, another as the bullet begins opening, and a third devastating impact when the specially engineered cavity fully expands to deliver extra shock and maximum transferred energy.

This is NOT LOADED ammunition.

Like the X-Bullet™, the Triple-Shock X™ features all-copper construction, no fragmentation, maximum weight retention and 28 percent deeper penetration than the best lead-core bullets offered. On impact, the bullet face opens to create four razor-sharp cutting edges. The Triple-Shock X™ ringed bullet provides significantly greater velocities, lower pressures and less fouling, without requiring an external coating. The bullet delivers a triple impact-one when it first strikes game, another as the bullet begins opening, and a third devastating impact when the specially engineered cavity fully expands to deliver extra shock with maximum transferred energy.

This is NOT LOADED ammunition.

The Xtreme Defense (XD) Technology is based on the popular Xtreme Penetrator product line. The design goal was to achieve the same barrier performance and massive permanent wound cavity and reduce the penetration depth to coincide with an individual's personal comfort level. It was a goal we did not meet; it was a goal we blew out of the water!

• Progressive nose geometry 18" penetration depth range
• A permanent wound cavity (PWC) that is 2 times greater than any expanding bullet
• A PWC near that of a 5.56 rifle.
• Reduced recoil.
• CNC machined from solid copper to overcome barriers to penetration
• Radial flutes that force the hydraulic energy inward to build pressure
• Minimal surface area to increase the force at the point of contact and sharp cutting edges that defeat barriers

Sierra offers a single flatnose bullet in this 45 caliber specifically for the 45-70 bore size. It may be used in rifles or handguns with a .458 inch bore, but it must not be used in handguns with .451 or .454 inch bore size. Sierra introduced this bullet in 1973 -  the 100th year of the 45-70 cartridge. Now, decades later, this old cartridge is still growing in popularity and justifiably so. Adequate for any game in North America and offered in several modern firearms, this old cartridge is just plain fun. The bullet is unique in that it expands well at modest 1873 Springfield velocities or at the more powerful full charge velocities that can be loaded in stronger action types, such as the Ruger No. 1 and No. 3 and Marlin lever actions. Accuracy is excellent, and it feeds reliably through all types of magazines and actions. It can be used in the 458 Winchester Magnum cartridge, but muzzle velocities should not exceed 2500 fps. For handguns, this bullet was designed to expand reliably even at 1300 fps.  It is a perfect match for the T/C Contenders and similar handguns chambered for the 45-70 cartridge. Dependable expansion and excellent accuracy make this Pro-Hunter bullet a good choice for most hunting situations. This is NOT LOADED ammunition.
