How difficult to change a winchester mag into a 416 rigby?

This is a long term plan that I will work on at a relaxed pace. The idea is that I get a winchester stainless action, add a chambered stainless barrel, and put it in a stock of my choice.
Those specific things I have listed, I am familiar with.

What are the things I am missing? Lets assuume I start with a winchester 7mm magnum.

I'm hoping this isn't overly involved. I can do some of the work myself, some I will have to send to a smith.

I wouldn't start with a 7mm Mag I'd go a little closer to the end round.
Bottom metal or at least box mag work including a new follower, Open the bolt face, extractor work, possibly bolt stop work, Then get it to feed. Add cross bolts to stock, possibly a second recoil lug.

As much as the Rigby name carries it's own prestige the .416 Rem Mag would be a better choice. still launches a 400 grain bullet @ 2400 FPS it is on par with traditional rigby performance with a lot less work needed to the action.

I plan to get the new ruger 416 in the handy 20 inch barrel version when it comes out. I think that is pretty much the equivelant of the 416 rem mag.
The idea with the winchester is a slightly longer barrel and more powder to get more velocity. I was under the impression the rigby would better the rem mag by about 200 fps. If they are all the same I will reconsider this plan.

Well yes and no
The original Rigby specs were for cordite and the case capacity is huge. If the brass has been upgraded to handle 65Kpsi go for it. I'm not sure the if the brass can or can not handle the extra pressure. It may be fine.

Nightmare. The winchester custom shop perportedly made TWO, even though this was a standard offering online for several years, due to feeding issues

The 7 remmag length action is the long action. Bottom is the same as the HH only top is different.

This was my understanding as well.

On guns international there is a Champlin stainless synthetic 416 Rigby. The action is a model 70 clone made by Champlin, not their other proprietary action. $4500. Double square bridge, already scoped with B&L glass. Very nice. Looks like a really good value for a stainless custom 16 Rigby Rifle.

FISH!!

Heed the words of Winston Smith in Orwell's 1984:

"Every record has been destroyed or falsified, every book rewritten, every picture has been repainted, every statue and street building has been renamed, every date has been altered. And the process is continuing day by day and minute by minute. History has stopped. Nothing exists except an endless present in which the Party is always right."

I've seen one or two model 70 416 Rigby's on the web built by Sterling Davenport. You might call and ask him how it is done.

IIRC those custom shop 416's were only actions and never were completed by Winchester. I think when the custom shop closed they went to a vendor.

That's all I need to hear. I'm out of this.

A little over my head. Could you explain with a bit more detail? HH?

On the M70 the actions are the same for the 7mag length and 375 Length. The bottom metal has a spacer installed in the rear to make the box shorter for the 7mag. The ejector and bolt stop are both shorter on the 375 to allow the bolt to reach the rear of the longer mag box.

You can alter the lower metal and ejector and extractor from the 7mag to fit the longer but it is easier to simply buy the longer to begin with.

I think the ejection port is a little longer on the 375 style.
