From FoxNews:
Hopefully since he didn't actually shoot at anyone there won't be as much heat from the gun aspect. Could have been a .50 desert eagle or a S&W .500. I really don't see how he could manuever a Barrett or some such other large rifle inside the confines of that bulldozer.
Holahan said Heemeyer was armed with a .50-caliber weapon but appeared to be deliberately avoiding injuring anyone during the rampage, which began Friday at about 3 p.m. No other injuries were reported.
