I'm doing the 2-day. Was originally planning to use my DMR style AR for the whole thing, but now I'm reconsidering using a 22LR for the first day (when I think all the shooting is done with reduced targets at 25 meters), and then breaking out the AR just for the 2nd day when I think they'll be doing actual distance shooting.

Can anyone who has attended offer any feedback on this? Assuming I do this, I'll probably pick up a new 22lr rifle, probably a simple 10/22. I've got a decent 3-9x40 scope I'll throw on it (my old eyes suck with iron sights).
