ok, yall got me a little interested in this after reading all these replies, so some questions.........say I have an old 760 30-06, I get my gunsmith to rebarrel it to .338-06. Can a pump handle the extra pressures needed to get the performance desired outta this round?Or would it be better to use a bolt action for this project? And can the average person take a 30-06 casing and squeeze a 338 bullet into it without modifying the casing any?

oh and another thing, where would i find dies?
