I also found this site last night. It was made by a WWII reenactor who owns and shoots his own MG-42. He also has access to some other WWII era MG's such as a russian Maxim, a MP-44, a .30 cal Browning, a .50 cal Browning. They also shoot a .50 cal browning Barret Sniper rifle. and several other cool weapons. I highly reccomend this site, check it out.
