whats the saying? “The more you know, the more you realize you don’t know” ? From the moment I started reloading 308 and 223 I’ve been chasing those one hole groups. Like a lot of guys on this site I started researching and realized the Remington 700 could be built into a “tack driver all day long” My first build somehow landed me with a Clarence Hammonds 6ppc that till this day shoots incredible. However the barrel life is short so I hardly ever shot it. Then I found myself chasing accuracy and barrel life in all the latest greatest calibers from 6.5 creedmoor to 6 creedmoor and even 30br. One of my recently built rifles is a 6bra that I’ve read promises unlimited barrel life. Then today I realize holy smokes side by side it’s dam near identical to the 6ppc I’ve been to scared to burn the barrel out of. What gives? Why is the 6ppc said to last 1000 rounds or less but the 6bra is supposed to last a lifetime? The 6ppc load is 68 grains while the 6bra is 105.
