action wrapped in alloy tape so the finish wont get marred, installed in the wrench, and in the barrel vise, chalk used to mark the witness mark on the action..a cheater pipe was used to tighten the barrel in the vise.

barrel removed!!!this one was easy, usually i have to use the cheater to get the action free from the old barrel,
at this time, check for damage, cracks, rust ect, in the opening of the action, clean with a solvent, i use brake parts cleaner, also use a small rifle brush, and a rag to clean this area. look for gualling of the bolt locking lug weighs. this one is in great shape. and reay for a good barrel.
word of caution, dont leave the wrench on the action with out a barrel installed for a long period of time, it will warp the ring..an hour or 2 is all id leave it without a barrel installed.
if you need to work on the action, remove the wrench or loosen the bolts that hold the wrench on.

new, used barrel , ready for install, notice chalk line on the Rear sight base step line, that the wintess mark that meets up with the one on the action.
pictured is how far apart the lines should be when hand tight, closer is OK, farther may give you issues when it comes time to line them up.
last picture...is the lines set, correct witness mark line up.
if the barrel slips in your barrel vise, some 200Grit sandpaper, grit oround barrel, will grab the barrel enough to get one good turn, cuation, dont let the barrel slip in the sandpaper, or it will remove finish, careful not to over index the marks...

check sight alighnment with a small bubble , as shown, this is important on the 1903..this wont work on the A3, and sight alingment is best checked by eyeball on that model.
if your sights are off with the action, you will need to adjust with the action wrench ect.
if the front and rear are off, then you will have to set the action to the front sight, and then drift the rear base as needed.
the front sight is keyed in place, and harder to move then the rear base.

home stretch..since this is a used barrel , its not short chambered, most new barrels are short chambered and will need finish reamed, i will touch on that another time..
anyway,
check the action with a action proving dummy round, they are black colored and available on line in any cal. with the firing pin assembly removed, or use a live factory round, safety first...be very careful, and make damn sure the cocking assembly is removed...as well as the trigger.
make sure the bolt closes easy, and smooth.
then check headspace with a No-Go gage, it should close to the same point as pictured.
then comes the test fire.
i use a factory round...not a GI ball...they are usually loaded pretty tame, and are safe to use.
the one pictured is a Winchester silver tip, i buy factory at shows with a round or 2 missing, simply for test fire.
after the round is fired, remove the case, look for signs of pressure, case head squat, primer deformaty, ect.
run a brush down the barrel, assemble and clean, enjoy....remember, use good tools, wear safety glassses, gloves, and use common since....

ok,, thats it... all in all its a pretty basic job...poor quailty tools can make it hard.
removing the old barrel can be a bear...if you not done one before, have someone has walk you through it, and or help...

Chuck,
Thanks for posting the info! I am pleased with your knowledge and sharing of said wisdom!
I didn't see where you mentioned lubricant on the threads. Do you lubricate the threads as you tighten the barrel to the receiver... and if you do... what type do you recommend?

That is a cool post Chuck! I don't think I'll be doing that anytime soon myself, but I love to know how things like that are done. Maybe there is a local guy here who could learn from this (wink). Is the action wrench contoured close to the shape of the action?
