Safety considerations require rifles equipped with tubular magazines to
be loaded with flat nosed bullets only. This ensures that the
cartridges will not ignite one another. While safe, these bullets
travel only at moderate velocities. To address this, Sierra has added a
series of features to promote reliable expansion. Two of the bullets
offer a hollow point design in which a large frontal cavity promotes
rapid expansion on impact. In the 30-30 and 375 Winchester bullets,
Sierra offers a Power Jacket which features a series of "skives" cut
into the mouth of the jacket which allow for greater expansion at lower
The traditional, flat base design of the Pro-Hunter has been skillfully
blended with Sierra's world-famous accuracy. The custom-tapered
Pro-Hunter jacket design helps assure maximum expansion, optimum weight
retention and deep penetration for game-stopping, 1-shot performance.
