I am wondering if anyone would know what happened.I fired a round with 86 grains of Retumbo,200 Accubond,Fed215m primer COL at 3.595" Fired like any other round except that when i removed the case there was a 1/16 dia hole just below the shoulder.I have never used this powder before and I did not fire anymore until i find out what happened. The brass i used was shot maybe 3 times prev. with different loads. Suggestions??
