Sierra Sports Master 40 Caliber/10mm (.400 Diameter) Bullets 180 grain Jacketed Hollow Point Box of 100

These bullets are designed to meet even the most demanding shooter's needs. This bullet was introduced in 1988. They provide 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. The International Practical Shooters Confederation needs only 917 fps muzzle velocity with the 180 grain #8469 to make "major." These power factors are easily attained with the heavier bullets in the 10 mm 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.

This is not loaded ammunition.
