Speer cold-formed lead bullets have been a great bargain ever since Vernon Speer introduced them over 40 years ago. All Speer lead bullets now feature a hi-tech, multi-layer lube system. This great lube stays with the bullet instead of burning off. It won't melt off in storage or transport, and is clean and dry to the touch. Lead Round Nose Bullets are suited for a wide range of shooting applications and are a perfectly suited for use in revolvers. Primary function is target shooting. This is not loaded ammunition.
