There are two philosophies when it comes to bullets. One believes  rapid expansion, moderate penetration, and weight loss are best, while  the other believes that moderate expansion, deep penetration, and  virtually no weight loss are best. Both have their virtues and  applications, but why settle for one or the other when you can have  both?  Controlled Chaos ® bullets offer the best of both. Once fluid is  impacted, they shed the front portion of the bullet into multiple petals  that radiate outward away from the bullets initial trajectory path  resulting in a massive energy spike. The bore diameter base of the  bullet continues and penetrates deeply in a straight line. Both the  temporary and permanent wound cavity created by this bullet separation  is dramatic resulting in quick incapacitation.  The solid base creates  additional tissue damage and often results in full penetration of the  animal.


This round is designed to fit and function through standard short action rifles with standard twist rates.  This is round is Lead Free. 


We measure each powder charge to within +/- .02 grains on our Autotrickler powder systems.  We seat each bullet with Redding competition seat dies on our Forster Co-Ax single stage press.   We load them one at a time!  Each round is hand measured for consistency and placed into our hard plastic, twenty count boxes.  Each box has a foam insert and neoprene strap to keep your rounds secure in the field.  This is loaded ammunition.
