Description

Designed to replace the 375 Weatherby Magnum, deep penetration and bone smashing power are the calling cards of the 378. Its massive case holds so much powder that Federal designed its super-hot 215 primer to handle the load. Roy Weatherby’s 378 delivers 34 percent more energy at the muzzle than the powerful 375 H&H Magnum. Since 1955, the 378 has become one of the world’s most popular cartridges for the largest of big game animals.

    Hand-load results: three shots under a quarter at a hundred yards with the Sierra 300 grain boat tail.

    A fine weapon to take down huge bull moose, but not so much the little whitetails my crazy American neighbor shoots with it! I think the bullet field dresses whatever is left of it!

    As a long range caliber it’s hard to beat the 378 weatherby ..

    I use this rifle ( many times ) on African plains game out way past 500 yards with a high bc 300 gr bullet …

    This is my ultimate hunting experience ever !!

    One shot kills when hunting boar is guaranteed. Exit holes like the bottom of a beer stud.
    If you want just to “plink” around, 0,5″ groups of 3 shots at 100 yards are not uncommon if you do reloading with Barnes TSX bullets.
