Very Low Drag (VLD) Bullet Specifications

 For Specsifications on our
Low Drag (LD) line of bullets go HERE

  All of JLK's bullets (unless otherwise stated) are true VLD (Very Low Drag) designs. Original specs for the forming dies that Jimmy Knox had made are derived from drawings produced by famed US Army ballistician Bill Davis, Jr.

  All of JLK's bullets are made of the finest lead that we can get our hands on and the absolute best jackets in the industry.... the J4 jacket.

All dimensions below, unless specified otherwise, are in inches
