About Product


These bullets are designed to meet even the most demanding shooter's needs. The 135 grain #8425 bullet was new in 1996. Providing rapid, controlled expansion for defensive use or on game up to large varmints at ranges out to 100 yards. Their unique design also produces excellent accuracy for competitive events.  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.

The #8425 was introduced in 1996.
