Then either a 338 edge or 7 STW

I'm doing one also, and using 270 WSM brass. Necking down will be easier.

Depends...
If this crap comes to pass.... 50 cal smoke pole CVA Acurra V2
If it don't...... MG42 Sub machine gun. I have to build it from parts. No biggie. Built one already for another person. 8mm Mauser belt fed over the top....or a Vickers or Browning liquid cooled.....
1200 rpm standard weight extractor, 1800 rpm lightened extractor....
Not terribly expensive to build but expensive to shoot.

The MG42 isn't a sub machine gun it's a full auto only 8mm Mauser(7.92x57)Machine gun. It was the primary machine gun of the German forces during WWII. It was without a doubt the best automatic rifle/light mg of the war.
I think you are confusing it with the Sturmgewehr 44 which was select fire and fired the 7.92x33.
The designation "sub machine gun" means it fires a mid range cartridge between pistol calibers and battle rifle caliber.

What is a 7mm AM ?
The only thing I can think of is an "Arnold Magnum" which would probably be an 8mm Remington necked down to 7mm.

Recommended Uses: The 7mm Allen Magnum was the first APS wildcat to step away from the Remington Ultra Magnum parent case in favor of a slightly shorter and fatter design based on the 338 Lapua Magnum parent case. The reasons for this change are for the slightly larger case capacity but mainly due to the dramatically increased strength of the Lapua case allowing it to handle pressures far exceeding anything the RUM case can survice and do so with long brass life with top loads. The 7mm Allen Magnum is also the first APS wildcat that is designed and fully capable of harvesting game up to 1000 pounds at long range. With the use of the 200 gr. ULD RBBT Wildcat Bullet, nothing else will match the ballistic performance of the 7mm Allen Magnum unless you step up to the wildcats based on the 408 Chey Tac parent case.
Using 140 to 160 gr. Accubonds, the 7mm AM is simply amazing on deer size game up to 400 pounds. For light weight sporter rifles, these lighter bullets produce lower levels of recoil yet retain plenty of terminal performance for medium big game hunting.
Effective Range: T he 140 gr. and 160 gr. Accubonds are fully capable of cleanly harvesting small and medium big game at ranges up to and even exceeding 800 yards. In ideal conditions these bullets retain plenty of velocity, energy and accuracy to harvest medium game out to 1000 yards.
The 175 gr. Sierra MK, 180 gr. Berger VLD and 200 gr. ULD RBBT Wildcat Bullet are fully capable of harvesting deer size targets at ranges WELL past 1200 yards. Referring to the velocity performance chart above, the 200 gr. ULD RBBT retaines well over 2200 fps and nearly 2200 ft/lbs of energy at 1200 yards!!! While this level of performance is enough to harvest elk size game at this range, it is still recommended that elk size targets be held to 1000 yards max with the 7mm Allen Magnum. This is mainly due to the relatively small frontal area of the 7mm bullet.
Pros : Fully formed brass available from APS with rifle orders. Can be used with powders that are very stable over wide temp changes, Extreme ballistic and terminal performance, limited recoil, relatively short over all length works in standard length receivers and magazine boxes.
Cons : Somewhat limited barrel life (plenty long enough for a career of big game hunting). Large diameter Lapua parent case requires receivers designed for this class of chambering. Best bullet for this chambering is the 200 gr. ULD RBBT which is a custom bullet made by Wildcat Bullets. This bullet is in production at this time but as a custom bullet availability can be a slight issue.

What twist of barrel for a 7mm Allen Magnum with 200 gr bullets that I may never see?
Have you ever used Vihtavuori N-570 in the 7mm Allen Magnum? It has become my powder of choice with 140 and 160 gr bullets in the 6.5 WSM. When I build a 7mm to shoot 180 gr Bergers it I intend to use VV N-570 or Retumbo.

Guess it depends on what you call big game, In my book anything sub .30 is not a big game gun. My definition is, it must be able to pass compleetly through what ever your hunting at any angle !

I classified it as the C&R approved list classifies it. BATFE C&R classifies it as a sub machine gun. The one I built woud run in full automatic and short burst as well as single fire. It's 'Hitler's Buzz Saw' as Allied troops nicknamed it....
DPMS sold the components at one time, not sure if they do anymore. The barrel carrier and muzzle section was made right here in Michigan BTW. The stamped steel barrel carrier was laser welded, I was very impressed with the overall quality.... and the amount of machining required.
I'm very familiar with it. I was 'married' to it for almost a year. 8mm Mauser, belt fed, over the top, interchangeable barrels and extremely industrial looking.

The way things currently are (and who knows when they will improve), I may consider any caliber (for my next rifle) that I can obtain easily, or an oddball that you can obtain components for.
I did just receive 6 boxes of 50 grain 223 V Max ballistic tipped from Hornady without waiting too long for a customer. I was amazed that I actually got them this year............
My favorite brass supplier has suspended taking orders entirely. Least I got an order in before the suspension for 223's and 308's but I'm still looking at 2 months lead time....
This sucks...
