JLK Bullets
Very Low Drag (VLD) Bullet Specifications

 For Specifications on our
.224 cal. 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 dimensions below, unless specified otherwise, are in inches
All dimensions are nominal.

 HUNTING vs. TARGET bullets.....
Please note that JLK's projectiles are quite suitable for use in the hunting field. The same qualities that make other brands of VLD bullets good for hunting come though in ours as well. In point of fact, several Custom Long Range Hunting Rifle builders use our 6.5mm, 7mm, and 30 cal projectiles in the custom loaded ammo they sell with their custom hunting rifles.
Our smaller caliber .224 LD projectiles are quite popular with long range varmint and small game hunters as well.
