Not Working

Blowing out primers on a 5.56 mm chambered rifle that has not experienced any blown primers through numerous lots of IMI, Lake City, and PRVI 5.56mm ammo (I collect my brass so I would know). Blown out primers sometimes jam up the bolt or the trigger mechanism. ........not a good show Hornady.

Several hundred rounds, no problem.


I have shot 500 round so far without issue. I'm not disputing what the other guy said. I just know I have run it through 4 or 5 rifles at a shooting day and we had no primers fall out all day. I have bought a few hundred more rounds and will continue to shoot it.

Kudos to Hornady


This is Hornady bullets loaded by Lake City Brass great combo. An outstanding price

3000 rounds and no issues. Great bargain!

On my 3rd 1,000 box of this ammo. I have had very good results with this ammo with S1/7 twists barrels from 7.5” to 18” match barrels shooting suppressed and Unsuppressed. I also have managed to produce several 1/2 inch groups at 100 yards is in a match barrel. Blown primers are not always excessive pressures from the cartridge but may be a timing issue with a semi automatic gas operated. However if you’re experiencing blown primers and the primer will not fit back into the pocket chances are it could be an over pressure issue. Contact Horner day with the lot number and inquire about the tested ammo which they should have a record of. For me this is great ammo for the price.
