Just a reminder too all 700ml owner make sure front action screw doesn't thread more than 3 1/2 turns deep. At about 4 1/4 turns action screw contacts barrel tenon threads.
Had my first seized 700ml stainless action to barrel last night. Yuck.
I feel barrel was dry fit and definitely action screw damaged tenon threads.
I set up in mill and plunged thru action screw hole to relieve damaged threads first with 3/16 end mill. Then setup in barrel vise light heat on action to release locking compound but none present bad sign. Started to remove action way to tight finally popped loose turned 1/4 turn locked up .
So now to salvage action into lathe and cut tenon out of action. Obviously barrel is toast but saved action to live again.
Thread i believe were installed dry and action screw to deep and barrel way tight.
Lessons learned and move on.
Side note gun will be better than ever but costly

Good note Jeff! Probably would not hurt to put some Kroil or penetrating oil in that action screw hole. Or even force some anti seize in there. Another hint............After fitting a new barrel, mark the center of the threads thru the action screw hole. Remove the barrel and run an end mill down to remove the threads under the action screw hole. This will allow the action screw to fully engage the threads in the action and you don't have to worry about crushing the threads. I also like to keep the bottom of that action screw pretty flat so I get full engagement in the action.

been there done that early on, was a valuable lesson, now I always check the threads to see if someone has bottomed a screw out before I try to remove it. A good reminder to all members..

I cured that problem quite a while back. I install all my barrels with a relief cut in the barrel so I don't have to worry about screws bottoming out. I have had several Rem M/L'S that I bought for actions That had smashed threads from front stock screws bottomed out into the threads and many with scope screws that also hit threads they can be bad news. You got to relieved those damaged threads or they can damage the threads in the action when you remove the barrel.
CF actions don't have this problem. If you front screw is to long your bolt will hit the top of the screw. You can also look in the receive and see if the screw is flush with the action or not.3 turns on a screw is not a lot when dealing with a 45Cal muzzleloader

It's a shame & I was talking to the owner of the gun today. Sometimes these things are beyond our control & they just happen. In the long run he's going to have an even better shooter than he had before & it will be done right.
