This sound like it could cost me some money!
This good news ,you will be busy!

What contour is the barrel on the 700P?

That was a shilen #7HV finished at 28"

Oh boy ..... here we sit with sooo many unfinished projects/builds on the go, looks like much of my cash will be headed west.!!

Are you doing bolt handles?.

This is Good News, Jerry.

[Mystic Precision]

Yes, we are putting on knobs for handles - Rems and Savages. $60 plus knob.

The $250 for an aftermarket barrel install, is that from a barrel blank? Would a pre-threaded/chambered barrel be less?

question,
I see in the picture the action appears to be CM and the barrel is stainless, its okay to mate those two together?

I know in the industrial world (currently working in the oil sands) letting those two touch eachother is a big no no, when fittings of different metals that have different electric potentials (such as carbon and stainless) are threaded to eachother corrosion can occur between them, usually in the case of stainless and prettymuch everything else, stainless begins to corrode the other metal, they kinda try to trade electrons with eachother and the weaker one usually breaks down. People usually call it just "dissimilar metal corrosion" sometimes it obvious, you can see the carbon oxidizing and the stainless just getting a little surface rust and sometimes you cant see it with the eye but one metal is breaking down and becomes very brittle and goes a little out of preportion. (can be spotted with xraying and ultrasonic)
I've seen it where dissimilar metals break where they mate or one just degrades and throws the whole little line out of line (usually in shoddy workmanship where someone just scabbed whatever fittings and nipples they could find together) which if this occurs in a rifle could make it shoot off in whatever direction the barrel is stressed on from the action. The action where the barrel mates to it could "oval" a little bit or shrink on one particular side adding a bit of stress to the barrel and changing its orientation.

Usually it doesn't become a problem till an energy is introduced (electricity, heat or the constant flow of liquid through the pipe making a little charge) but with all the heat and energy and friction of a bullet sliding down the barrel of a rifle its gotta make a little bit charge to assist with the dissimilar metal corrosion process. But this is just my thoughts, It's evident in industrial application, stainless-carbon-stainless-carbon whatever from fittings to valves always gets an inspector fail in my work.
Is there something about the rifles that prevents this? perhaps the blueing coat on the action or a barrier fluid applied to the threads of the barrel before it was put on.
People have been putting stainless barrels on CM actions for a long time so there's gotta be something that prevents dissimilar metal corrosion or no one has really noticed the gradual breakdown over a period of time and may mistake the accuracy drifting for the scope may be losing zero and needs a re zero after a few hundred rounds or a bit of rust showing up as a lapse in maintenance or a corrosive primer or whatever else usually rusts a gun. Or no visible corrosion or degrading but the rifle losing accuracy and action becoming a bit weaker as "just a gun getting old" because the action could be degrading, people just cant see it.

Like its gotta happen, it happens everywhere else, leave a stainless fork on the bottom of a normal metal pot for a month or two you'll usually see a rust line where the fork was touching.

Please tell us you don't work in any restaurants in Alberta.

To install a prefit barrel onto your action and do the final headspacing is much less. In general, this is $50

As you have said, many many many rifles have this combo. Many are also on match rifles that seem to put them into 1 hole. We have not experienced any issues either short or long term.

I will leave the actual science to someone more qualified but the holes in paper speak for themself.
