Lots.www.68forums.com/ EDIT- Ok, I obviously haven't been over there in a while, as I just pulled it up and found, well, not much. They've still got their sponsor links up, and the board is there, but no forums. Not sure if they're just working on it or what... Keep an eye on it, though. Good info there.I will say this, though. For general use (and for some specialized uses), Silver State Armory is the best 6.8 ammo I've used. You can order direct from them.
There's a few forums doing that same thing: FN forum, one of the many 1911 forums etc. Actually I was given a little access in the beginning but then they pulled the "if you want to see more join our forum" thing. Bummer.
