I may be a little biased, having earned my Rifleman patch, but it was a LOT of fun. I have been shooting for several years (granted, mostly handguns). Even so, and not surprisingly, they had new things to teach me. I did my best to learn.
Most likely, you will be sore and tired at the end of the weekend if you go, but I highly recommend it. I really enjoyed the instructors, and the other shooters. Best weekend I've had in a long time.
