I've fired the 69 through layers of wet paper, and it makes a huge wound cavity. I should not like to experience being smitten with one.
I’ve always preferred the M193 load in our ARs and M16.The bullet usually breaks up on impact,at least at close range.For serious zombie kills,I’ll use my Remington 700 tactical in .308 or my HK91 if they start getting too close.
