Losing Bullets

Written by Sierra Bullets Ballistic Technician Paul Box

From time to time I get calls about shooters “losing” a bullet.  This has become more common from the .204 Ruger than any other caliber that I can remember.

Losing a bullet is not referring to the one dropped on the floor and rolled under the bench that you can’t find, but rather a bullet that didn’t make it to the target.  More times than not, it is caused by a throat that has become “heat checked” from several firings over time.  These little cracks can have sharp edges that damage the jacket and results in a bullet coming apart in flight.

With some calibers, it’s a good habit to get into scrubbing the throat area with a bore mop and JB bore cleaner.  This will smooth those rough edges reducing the damage to the jacket. A good scrubbing in this area every 400 rds. will go a long way to stopping this headache.

    Wow, never heard of that but makes very good since. I often have a problem from my .223 doing this also, I thought it was me.

    Paul’s 100 % correct..I had a .257 wby that would seemingly dissolve my 90 gr game kings. granted they were moving pretty fast,but after talking to Paul & using some JB’s ( along w/slowing them down a bit ) there were holes appearing once again in my targets….
