These bullets are designed to meet even the most demanding shooter's needs. This bullet was introduced in 1992. The 165 grain #8445 requires 1000 fps muzzle velocity to make "major." These power factors are easily attained with the heavier bullets in the 10mm Auto or 40 S&W. One also can use any of these bullets in an "old timer," the 38-40 Winchester (38 WCF), made popular in both single-action revolvers and rifles for Cowboy Shooting. However, these bullets are not legal for competition. Special provisions may be required for crimping (since these bullets have no cannelure for roll crimping) and expanding ball size in reloading dies for the 38-40.
