Never had a hamBurger bullet fail to open after I meplat uniformed and countersunk the meplat with these Montour County Rifles' tools. I own the meplat unforming tools for .224, .284, .308, and .338 caliber bullets.
I thin out the leading edge of the meplat with the countersinking tool more than is shown in the below picture. Creates a catcher's glove for hydraulic opening of the tip of the jackets.
I don't use Burger bullets for hunting any longer. Meat shredders. I prefer to grind my game in my meat grinder.
