I like this for a couple of reasons.
1. I really like discussion different scopes for long range
2. Sharing info on ammunition accuracy
3. discussing ballistic coefficients
4. Most people don't want to talk windrift, holdover, and calculating your dope.
I use Reddit.com/r/longrange from time to time for talk that I would designate marksman.
I'm also interested in a good Ballistics calculator for the Iphone, I've even seen MOA calculators for very good calculations on exactly how small your group is.
These 4 reasons could not be said better, IMO
