How do you change the barrel on a 700 Remington rifle?

Theres your wrench.

I do not own a 700 nor am I a gunsmith. If you have the new barrel now, I'm sure a gunsmith would be happy to accomplish this within 20 or so minutes. You may have as much as 75,000 psi in there when you pull that trigger. A bad round/barrel bolt assembly and you have a bolt sticking into the soil berm after reaming out your skull. These are not toys.

Before disassembly look for either a driftpin or setscrew. You will need to have the barreled action out of the stock to do this. You will possibly need a drift punch the same diameter as the roll/driftpin in there holding it together. Also, lookup headspace gapping. This is the adjustable distance between bolt close and casing neck contacts the barrel. It shows up where the receiver meets the barrel. You will need a GO/NOGO gague for this, and theyre usually model specific. It will be able to slip into the crack, but not beyond a certain point. If its within those ranges its a go; pretty simple there.

Im assuming that you do already know if your new bullet will fit the new barrel AS WELL AS the bolt. Take for example a .308. .30-06 and 270 have the same rim diameter. Also 300 and 300 RUM for obvious reasons, but not the 338 and not necessarily every 300. Do your research with this stuff before you go tinkering and end up on the news.

Check out any of your online forums for smithing. I would recommend SnipersHide.com. They have some of the best community forums I've come across for not only intellectual but a desire to help. Dont ask stupid stuff, and try to be courteous back, we'll be glad to help.
