i had my 300 win mag re barreled. the cost was right around $200.00 labor, which included reblueing the entire assembly so it would match. i supplied a new take off barrel, that i bought off from gunbroker.com (now ebay is allowing them also) which i purchased for $35.00 including shipping. i am sure some people will say that those barrels have something wrong with them. but this is a sub moa gun again (it was before i had it re barreled also). though not quite as small of groups (.783 new vs. .486 with the old). i would have never had it done if i had not goofed big time and ruined the oem barrel. now, i will say this, just for the purpose of you fully understanding the wonderful things that can happen. i am the 1 person, that if something can go wrong, it will. and it did. the gunsmith who installed the barrel, re cut the chamber to get the headspace correct. when he did that, he cut it out of round. then tried to blame it on "an internet barrel" he might have gotten away with it if i had not done a little checking first. the chamber was originally smaller that the one that was on my gun. and my fired neck sized brass would not fit in the chamber all the way. i figured he would most likely have to cut it, so i did nothing to my brass. when i got the gun home, my neck sized brass fell right in. so i knew he had cut the chamber. ok, fine, as long as he did not go crazy and make it huge. well, i fired a box of shells thru it, brought the brass home to neck size, measure and reload. which i did. but, the brass was egg shaped. i tried to chamber it, and sure enough, it got stuck. so back it went. to shorten this story considerably, i ended up buying another new take off barrel, that the smith paid me for. he did a chamber cast BEFORE he started to make sure there was no problem, which there was not. and i got the gun back with the chamber still correct the second time. all of this took almost a year. so if you go the new take off barrel route, have the smith do a chamber cast before he starts. that way if there is a problem, you will both find out about it before it is installed, and you can return the barrel, and get your money back. haveing a chamber cast done first would have saved me a lot of headache and hassel, not to mention money and time.
