[QUOTE="Bart B, post: 694852, member: 5302"] That's good. But you might want to decide what "accurate rifle" means for you, too. For example, what's the largest group any load has shot? To some folks, it's the smallest few-shot group fired. Doesn't matter if all the other groups are larger. Example, the record 1000-yard benchrest few-shot groups are 2 inches or less. But the many-group average for aggregate records is typically 2/3rds the size of the biggest single group fired. And rarely, if ever, does the rifle and ammo holding the record few-shot group also hold the many-group aggregate record; they didn't shoot well enough (too big of groups) to hold that one, too. To others, it's the largest many-shot group fired. That's what can be counted on the vast majority of the time. This is what arsenals do for military ammo; they shoot a couple hundred shots per test group 'cause they want to see what the accuracy level is that can be counted on all the time. One thing to note on group shooting; if all the groups fired with a given load are not the same size, you're not shooting enough shots per group to asses the load's performance to count on all the time. Another is, the smaller a given test load's few-shot groups are, the harder it is to shoot one that's smaller than the previous one. For example, which of the below sets of five 3-shot groups at 1000 yards is the most accurate: Group set A, ranges from 1 inch to 6 inches. Group set B, ranges from 2 inch to 5 inches. [/QUOTE]
