Speer Bullets 38 Caliber (358 Diameter) 158 Grain Lead Semi-Wad Cutter Hollow Point (500Pk)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. The Lead Wadcutter design features a sharp round shoulder that delivers superb accuracy and precision paper cutting performance.
