yes, it's 30-06 and it's not bad at all to shoot because it is gas operated. the 03 is also 30-06 that is a copy of the mauser action and is bolt action...no pad on the butt of the stock and it gets old quick these days lol I have an 8mm Mauser which hurts more and some Mosins which are the Russian equivalent to 30-06 and they all smart...one does not realize how much those rubber butt pads do until one shoots old guns with a metal plate on the butt
