Re: Removing Barrel from Action
hmmmm. I loosen the action screws and lift the barreled action out of the stock. I then wrap the barrel in a bit of newspaper to prevent scratching the paint on the barrel, put the barreled action into the barrel vice (with the action about an inch from the vice), insert the action wrench and turn with a bit of authority until it comes loose - no popping noises so far but that would be interesting. No heating guns or rosen are involved, but to each his own.
I also make sure to put a bit of anti-seize on the threads of both the stainless barrel and the action and spread it out over the threads before putting it back on and then hand turning the barrel back onto the action, when it gets hand tight, I reinsert the action wrench and put a bit of torque on it (maybe 20-30 inch pounds), and its done. As a right-handed twist, the barrel will self-tighten from there, if it feels the need, as the bullet srun down the barrel.
Next step is inserting and tightening the action screws, then torquing the action screws to the proper inch pounds, and I'm done.
To be honest, it sounds more difficult then it really is. In fact, the last time I swapped out the barrel on my F-Class rig, I was in a real hurry and left the scope attached to the action and it suffered not the slightest ding or scratch.
