The only 7WSM ammo I have seen was Fed Blue and Red at Gander before the local store closed. I don't recall seeing it locally but we only have a few options, maybe three choices in town and one is Walmart.

Yes, you can use 300wsm, because when you run it through a fl sizing die, it creates a false shoulder. Stay away from 270wsm though, because you would run the risk of case separation, due to excessive headspace. How would 300 WSM brass work and 270 WSM not work, when they are both the exact same shoulder length? The 300 would neck down, but you could easily neck up 270 to do the same thing. And BTW, all this is a very BAD idea! I've seen case heads separate on much less than .038" expansion. Someone who "knows" as "much" as you,is going to be farrrrr better served by asking questions...rather than giving "answers". Hint. Now as to Montucky 7 Whizzum's,I've only got a trio and reckon I should salt a few more away,if only for good measure. They've the RPM,throat geometry and COAL latitude,to connect all dots and are without doubt,the most Superb Killing Rifle ever offered over the counter and I've mused same more than a few times.(grin) The Montucky Whizzum handle is rather adept in managing felt recoil and Sister has loved her's,since a pre-teen. I savvy the appeal. Puked another set of LW's on one,not long ago and I think that's (8) sets that've puked on me...outta about 40 that were in service as mainstays. Though in fairness,this is the first puke,in that location and different from most other LW failures. Admittedly,said rifle is a Safe Queen.(grin) Lapped Of Course...RINKJust sayin'. Swore off LW's all together and started tossing schit offa cliff. I hear good thangs about 180 ELD's in same(2950fps),though the 162 'Max and 162 ELD's ain't no slouch(3125fps)...or so I've heard. 'Course I VERY much enjoyed your keen "understanding" of headspace,as you talk out your ass about the things furthest from your faculties...so PLEASE continue with your version of "knowledge","experience" and "results". Hint. Just sayin'. Bless your heart. Laffin'! Wow +P+!

I have several hundred pieces of new Winchester 7 WSM brass available, if you need ammo.
I would HIGHLY not recommend making 7 WSM brass from 300 WSM. The 300 WSM, 270 WSM, 325 WSM all have a shorter shoulder by .038". This would create a big stretch of the brass at the case web, and you would easily cause a case head separation upon firing. Chad, think of it this way. If you're familiar with Ackley Improved cartridges, they would not exist if there wasn't a safe way to blow out the shoulders of the parent case. With the AIs, the parent case headspaces on the shoulder where it joins the neck (assuming the chamber is cut right), and the cases don't stretch at the web when they're fired, they expand like a balloon. Same thing with a false shoulder, if it's done correctly the case headspaces on the false shoulder and it's blown out, not stretched. I have a few hundred pieces of WW 7 WSM brass too but the quality is poor so based on Jordan's advice I formed a bunch from 300 WSM. It works well.
A wise man is frequently humbled.

Well, it is in the truck.
Boxer, do you mind sharing at least your preferred powder for the 162 loads.
Jordan do you have any preferred loads for lighter bullets?
Thanks guys, you are all a bunch of enablers.

I’ve never seen a 7WSM, the 270 and 300 are great. The 7 should be too,
Does it have more get up and go than a 7 mag? It isn’t listed in my books.

R-26 is giving me 3170 with 162’s. The load is on alliant’s website. Work up to it because I got there a lot quicker than what their max showed.

R17 and 140’s is a good combo, and 7828ssc as well as R26 work really well with 162’s and 180’s.

I’m at 65 grains of rl26 and 180 eldm made it to 68but 65 shoots better. Was at 68 grains of RL26 with the 162eldx. Rl26 is pretty good stuff in the 7wsm

I’m shooting 67gr R26 with the 180 ELD. Same with 7828ssc for nearly identical velocity- 2990 fps from a 26” barrel.

I just picked one up off gunbroker. Gonna get a 3-9 Super Chicken
I probably hit more elk with a pickup than you have with a rifle. I have yet to see anyone claim Leupold has never had to fix an optic. I know I have sent a few back. 2 MK 6s, a VX-6, and 3 VX-111s.

Happy bday Jordan. The 56 was 65 on the fly when I posted sorry. Thanks, Fred! Always had such good results with 7828ssc that I never bothered with H1000. Though with all the talk of R26, I couldn’t resist, and it does work well.

I ran 67gr of R26 with the 180 eld-m’s for 3050 fps in my 26” Ga Precision 7 WSM. I had 9 loads in my Brass when I sold the rifle to go lighter and primers still seated snug as they did as virgins. Admittedly that barrel done gap seems to run everything about 75-100 fps faster then boom. I miss that rifle but it was a pig.

Ping pong balls for the win. Once you've wrestled everything else in life is easy. Dan Gable I keep my circle small, I’d rather have 4 quarters than 100 pennies.
Ain’t easy havin pals.
