Examples of this include the Hornady InterBond, Nosler AccuBond and Swift Scirocco. If maximum expansion and high weight retention are desired, bullets with the lead core and copper or copper-alloy jacket bonded together are the best choice. Plus the A-Frame’s front core is bonded to the jacket. Swift’s A-Frame and Nosler’s Partition incorporate a dividing wall in the bullets to stop expansion about halfway down their length. Bullet manufacturers achieve this performance several ways. Winchester factory-loaded 150-grain Power Point bullet clear through an antelope buck last fall, and with minimal meat damage.Ī bullet design that controls and/or limits upset upon impact is a good idea for shooting larger game. have filled freezers with venison for decades. Bullets like the Sierra flat-base spitzer (Pro-Hunter), Hornady InterLock, Remington Core-Lokt and other similar cup-and-core bullets fired from the. Ordinary bullets with lead cores and copper-alloy jackets work just fine on deer and antelope. That’s where today’s 150-grain bullets shine.Īn assortment of 150-grain bullets is available to provide a lethal punch. A bullet’s ability to halt the function of an animal’s vital organs is what dependably kills big game. in the 180’s favor.īut foot-pounds of energy do not kill big game. At 200 yards, the 180s do nudge ahead in the energy department however, at 500 yards that additional power is only 87 ft.-lbs. more energy at the muzzle than do the 180s. The 150s actually pack about 100 ft.-lbs. The 150-grain bullets also pretty well carry the same energy as 180-grain bullets. At 500 it’s more theoretical because nobody should shoot at an unwounded big-game animal that far away. That’s a significant advantage for the 150s at 400 yards. At those speeds, and with both bullets sighted in 2-inches high at 100 yards, the difference in drop between 150- and 180-grain bullets is 2.82 inches at 300 yards, 5.73 inches at 400 yards and 9.69 inches way out at 500 yards. The top speed from a 180-grain bullet was 2,770 fps. The highest velocity I ever attained from a 150-grain bullet from a. The trajectory advantage goes to 150-grain bullets in the contest between 150- and 180-grain bullets fired from the. Shooters are obsessed with numbers because figures help make sense of the mystery of the variation between different bullets’ trajectory and terminal performance. Their expanded frontal diameters were 0.575 inches and 0.770 inches with slightly more than half an inch of their shanks remaining intact-perfect! Yet both the recovered Triple-Shocks weighed 128 grains, shearing off two of their four petals. Few obstacles are tougher on a bullet than elk bones. The two Barnes 150-grain Triple-Shock X-Bullets had plowed through the lower part of both of the animal’s shoulder bones and stopped under the hide on its far side. The second shot also hit the bull in the shoulder, and it fell. shot was followed by a crack of the bullet hitting the elk in the shoulder. As he hurried across the flat to intercept them, the elk crossed 200 yards below, and a six-point bull at the back of the bunch stopped to change directions. At first light, Brian spotted 20-plus elk moving across a sagebrush flat toward the timber above. The result of my son’s elk hunt two years ago sealed the switch to lighter bullets for me. However, with today’s controlled-expansion bullets, that rule may have to be changed to shooting only 150-grain bullets at big game from antelope to elk. into the game fields knows that the traditional rule is to shoot 150-grain bullets while hunting game the size of deer and pronghorn antelope and to switch to 180-grain projectiles for larger game.
