I have a friend who has a 1903 and was told it was a 308 not a 30-06 so he tried to fire a 308 round and the case is now stuck in the chamber. Is there an easy way to get it removed or is it better to replace the barrel. It had already been sporterized so it wont be ruining it anymore than it already is. Is there a place in town that will put the new barrel on. Also what are your opinions on caliber? 338-06 or 35 whelen or something else other than 30-06.
