Another vote for the .375R.
If size and length is important, Personally I would suggest the Stainless Model 7 action for it's ease to keep clean and the mag length is the same as the short action mod 700. Overall length Is 1/2" shorter than the 700 SA.
A #3 or #4 contour in a Stainless will weigh almost the same as the carbon and in my opinion be easier to maintain and be more durable. I would also place a low power, light weight scope on it to save weight. Mine weighs just over 6 Lbs fully dressed. Just a suggestion for what it's worth.

Yes, I definitely saw the signs after the fact and pulled all the loads. Seems to be some "mysterious headspace" issues with this whelen as others have also experienced. I' ve had two gunsmiths look at it but no idea. So I'll probably rebarrel that rifle in the future as well- been looking at 9.3x62. So for this compact build was planning a .338 short mag - RCM or SS or WSM
9.3x62 is a very good choice. About the same case capacity but so much better bullets. And a wider shoulder for headspace. When the eastern Africa countries set the 375 as a minimum they made an exception for the 9.3. Poor mans 375Yes, I definitely saw the signs after the fact and pulled all the loads.

The brass supply has been the biggest problem with the 300wsm. Sorry if that wasnt clear. Reloading the cartridge has been fine. But I'm aware of only Norma, Nosler, Federal, Winchester and Bertram making brass for the 300wsm. Consistancy and toughness are the major deciding factors in brass for me. The older Winchester sounds like it was awesome. The new stuff is unpredictable. Federal, Hornady is garbage from what I've heard. Nosler and Bertram have been inconsistent from speaking to people. I've only seen small lots of both brass, and havent yet had time to form an opinion, but I'm not convinced it's amazing brass yet. Which I'm disappointed by as I expected Bertram to be better. That leaves Norma, and I hear good things but keep finding small lots of it and would prefer to buy in larger quantity.
I've spoken to alot of people and stores about brass supply for the WSM and no one has given me the warm fuzzy feeling about it. Which is a shame.
When I full length resize I take the rifle to the loading room. Start with the dire off the shell holder and keep turning it down to when the case chambers with no force. Understand a few thou deeper each time. Then lock the ring and you are there. Why I only own one rifle for each caliber.Yes, I definitely saw the signs after the fact and pulled all the loads.

Woodleigh which are very very good bullets make from 232 to 320 grain. Soft and solid. Protected point, round nose, solid, and a hydraulic stabilized solid. Like a Keith semi wadcutter pistol bullet. Similar, Nosler make a 286 partition. Something to be said for size. When I lived in Alaska I had a 375 weatherby on a model 70. I used it deer hunting on Kodiak. Floored them but you could eat right to the hole and I could stop a fight with big furry if I had to.9.3x62 is a very good choice. About the same case capacity but so much better bullets.

By the looks of the primer and swipe mark, was there a headspace issue? That looks like some good pressureView attachment 167948 The main thing I have against the RCM is Hornady brass. Bad experience with it in a 35 whelen. Out of spec, fail to fire, very soft, and this pic with a case head separation! Was shooting a 275gr Woodleigh in the whelen when it happened. I prefer not to use Hornady brass.....

I'd use a comparator on the cases of a fired v resized to see if that's an issue. I had a 300wm that a guy rebarrelled and I bought . Same issue with hornady brass separating. It was a hs issue, but yours might not beI don't know what the issue is (and two smiths try to figure it out, rechambered etc).
I would have factory Remington rounds fail to fire about 20% and then some would have swipe marks. Worked up some 200 ttsx jammed in the lands that worked. The Hornady brass was about 50% fail to fire. I have a box of federal that is 100% with no pressure signs. That case sep was a reload on Hornady brass with a 275 pp Woodleigh loaded with R15 per Woodleigh load data. No problem on the work up but shot a few off after a move and that's what happened (shot in colder weather even). Woodleigh data does seem high compared to others. Never the less I'm fed up with the 35 whelen issues so will rebarrel it down the road after I build a compact 338
That tells me your rifle was chambered too deep.I don't know what the issue is (and two smiths try to figure it out, rechambered etc).

What you said I have seen in 280 ack imp that somebody did on a 280 Remington. If you set up an ack imp and shoot regular case you need a .005 crush to hold it . Without the crush the firing pin bangs it forward and sometimes doesn,t go off. And when it does it stretches the case.That tells me your rifle was chambered too deep.
Consequently in a deep chambered rifle if you set the die to the shell holder you recreate it all over again.What you said I have seen in 280 ack imp that somebody did on a 280 Remington.
