Weatherby 30 Caliber Rifle Ammunition features a fully tapered jacket that will rupture instantly at the thin jacket mouth which then gradually thickens along the bullets axis controls expansion and curls the jacket uniformly outward at all velocities. Lead alloy duel core construction on the Weatherby 30 Caliber Rifle Ammo provides superior mushrooming at virtually all impact velocities. An Integral Partition supports the expanded mushroom and retains the rear alloy core and the enclosed rear core retains more than half the original bullet weight for deep penetration. Special crimp locks in the rear core section add strength to this 30 Cal ammo to resist deformation under the pressure of heavy magnums.
Weatherby Ammunition remains true to the concept Roy developed in the 1940s. At the same time, their ammunition also takes advantage of the latest in controlled expansion bullets which are capable of harnessing the higher velocities to create a cartridge that provides the ultimate in penetration, large wound channels and more one-shot kills. Nothing shoots flatter, hits harder or is more accurate.
