[QUOTE="bookworm, post: 572742, member: 13840"] Interesting formula Bart. I want to make sure I get it. If I apply it to a .308 I get around 48gr, which isn't too far from a standard load. Based on this...you are saying that a 1/2 moa rifle would shoot at that level for 5000 - 6000 rounds. And if I apply it to my .300WM which shoots around 1/2" and takes 78gr of powder...since this is a 62% increase in powder this would translate to something a bit less than half of your standard barrel life - or maybe 2000 to 2500 rounds. Do I have that about right? [/QUOTE]
