Re: Removing 700 barrel?
Tips:
Get a hot air gun. Milwaukee makes a good one.
Mix up a home brew of 50/50 Type F tranny fluid and acetone.
Barrel vise encouraged. Clamp the tube up close to the receiver along the cylinder portion of the barrel.
Hose it down with the ATF/acetone mix. Squirt some down the scope base holes. (REMOVE any/all bases from up front!!) Hose it down in the breech area too via ejection port.
Put the hot air gun to it till it smokes to beat hell. Get it RAGIN hot. The hot air gun warms the steel without ruining heat treatment, surface finishes, coatings, etc. Your not trying to do anything but break down the lock tite the factories use and promote some capillary action so that your "erl" mix wicks its way in there to loosen things up.
Insert your action wrench and using a breaker bar you'll have a drama free experience. No beads of sweat, no busted knuckles, no ruined receivers or barrels.
Good luck.
