Hunting with copper ammunition and projectiles is on the rise in the world of big game. There are plenty of performance benefits that come from shooting copper – not to mention the fact certain hunting clubs, wildlife management areas, and even states (Thanks, California) now only allow harvesting deer, elk, hogs, and other critters with copper. When you’ve got a buck in your sights and a full freezer on the line, can copper compete with traditional lead bullet performance when it matters the most?
Factors to consider when using copper hunting ammo:
Less dense and lighter-for-caliber than traditional lead projectiles, copper bullets are made from one solid piece of metal. When picking a copper bullet, look for long projectiles that stabilize well in flight and like the twist rate of your given rifle…meaning it’s important to choose the right caliber/cartridge when hunting plus test your ammunition at the distances you’re planning on shooting before you hunt. Don’t bring a knife to a gun fight, and don’t bring your 243 Win. to shoot a massive black bear at 500 yards, even if you are shooting tough copper bullets.
Copper bullets do not fragment, and penetrate deeply. Constructed from a solid, there can be no separation of the bullet’s jacket and core. These bullets retain their weight to penetrate through thick muscle tissue, or even bone, to reach vital zones. Lacking a soft lead core, copper bullets, without design features enabling expansion on target, (hollow points, exterior nose skiving, polymer tips) may “pencil through” game, creating a small wound channel and failing to transfer enough force inside your buck, bull, or bruin.
Twice as hard as lead, copper ammo really packs a punch. Breaking through shoulders on big game at appropriate velocities is usually not a problem for monolithic copper bullets, making them ideal for hunting larger animals like elk, mule deer, and moose or tougher animals like hogs and buffalo. At closer ranges, copper bullets are less velocity-sensitive than traditional lead cup and core bullets.
Early copper bullets gained something of a less-than-stellar reputation for accuracy with hunters also complaining about dirty copper fouled barrels. Modern copper bullets use driving bands to both increase accuracy by reducing pressure spikes when bullet enters the barrel’s rifling, plus reduce fouling.
