As I've said many times, "If you're good at sand bagging you only do it once."
Yeah, people plaque and match bump hunt all the time.
Interesting thought, to match bump you only need to beat 5 people at that day and time. But to do it via the classifier, you have to be ALL the people who shot it to get the numbers used. So bumping via the classifier is actually a skill "win" over a greater number of people.....
And yes, I was at the Nats where the 5x5 data was gathered and I did shoot it.
