The advantages of mono-metal bullets
EVERY so often, a new bullet comes along which offers improved performance and increased killing power. It alters normal parameters and changes the way we think about hunting projectiles. It doesn’t happen too often but, when it does, it ushers in a new level of technology that can be refined and improved upon.
Conventional non-bonded swaged-lead-core bullets are typically more accurate than any bonded bullet, but bonded bullets require a softer lead core, so they don’t always provide effective and consistent terminal performance at one or both ends of the velocity spectrum.
Today we have some excellent controlled-expansion designs, such as Nosler’s AccuBond and Ballistic Tip, Hornady’s Interbond and Interlocks, Federal’s Terminal Ascent and the Swift Scirocco and A-Frame, for example. Bullet development never stands still and improved designs keep turning up.
Today, mono-metal designs are becoming more popular for a number of very good reasons.
Barnes started the trend to all-copper projectiles more than three decades ago and for years I’ve been using their Triple Shock X-Bullet in my .257 Roberts for deer hunting. Long before the Triple Shock X, MRX and Tipped TSX appeared, however, I had been using the original copper X-Bullet in my .338 Winchester Magnum and enjoyed great success with it in Alaska as well as on other big game hunts.
Many shooters experienced problems with copper fouling using early Barnes bullets. This problem was solved
