Just noticed this thread and saw that nobody replied to your questions..... On the indoor pistol range (25/50 feet) no magnum loads, but .22 rifle also OK. On the outdoor pistol range (30 ft 25/50 yds) .22 rifle also OK. On the trap fields, target loads only, on the black powder range, black powder only, and on the high power range (50/100/200 yds) there are restrictions on what types of pistols can be shot, but other than that.. none that I can recall.
He cross posted in another WSA thread and I got him there, but reps to you for doing it as well!
