[QUOTE="4mesh063, post: 30759, member: 941"] After asking a question about group sizes needed to win in a short range BR match, I was given the following statistics. I had asked what was an average top 10 Match agg at 100/200 yards in the Light Varmint (10.5# class). The answer was .180" for 5 5 shot groups at 100, and .205 for 5 5 shot groups at 200. That means that they shoot, on average, about 12% bigger at 100% farther. Think about that. A PPC shoots almost no different at 200 than it does at 100, Yet, noone shoots them for LR. And what's more, just like it's said above, they dont even weigh powder out when they load these things. It's just too small an error at the ranges they shoot. While at 1K, it's a must. If anyone had all the answers about how a bullet flies, They'd be writing a book. I've heard so many tales of how a gun shoots real well at one range and real bad at another, I couldn't count them all. I have done it and seen it myself lots of times. There's just too much going on after the bullet leaves the barrel to have an explaination for it all. About the only answers you're gonna get on this question are opinions and estimates. Every one of them may be correct or incorrect to some degree, or under a particular set of circumstances and not under another. [/QUOTE]
