[QUOTE="MagnumManiac, post: 2874207, member: 10755"] Ok, have followed up on this and read the replies. When changing barrels, even with a prefit, there is no way both barrels will print to the same aim point. So you set zero stops for one barrel, then note where it zeroes against that barrel and record it. As the scope is attached to the action, no scope juggling is needed. I’ve been doing this for more years than I care to remember. I use a Davidson barrel vice and rear entry wrench, there are several styles, but I prefer that it goes all the way forward into the front action ring, less torque is placed on the rear of the action and I have seen a guy totally twist an action into a pretzel. As long as the machining is tight, no amount of torque used when tightening the barrel will change headspace, this is how it should be done. Now, sometimes, like my 7STW barrel, that had the shoulder altered to fit the new thicker recoil lug, will no longer orientate with the stamping in the same place, it’s slightly off centre, but it matters not to me. A Mark V won’t have this issue. Cheers. [/QUOTE]
