I recently purchased a Winchester Coyote in 25 WSSM with a SWFA SS 10x42 for 300$.

I couldn't pass it up.

I'm waiting on my dies to come in but I can not find brass to save my life. I have 30 rounds of spent brass and 30 rounds of factory ammo.

Is there any other casing that can be sized to 25 WSSM or any leads on brass?

I have thought about buying a new barrel and having the bolt worked to another caliber but I love the way this gun shoots.

Thanks

Any of the wssm casings can be necked to 25wssm. That's about it.

You'll have a hard time re-barreling this rifle to anything else (I have one- I know your dilemma) as winchester used a shorter than normal action for the wssm rifles and a mag bolt face. Possibly replacing the bolt and going with the 223 family, but I'm not even sure about that. Midway and Graf's do have ammo in stock for you to shoot to get brass; I know it's a pain but many times you have to shoot factories to get brass for your stuff.

This problem is not specific to WSSM brass. Pretty much all cartridge reloading brass, across the board, is in backorder.
It's just a bad time for ammo component purchases.
I'll look at what I hold & maybe I can let go of some.

You don't want to mess with necking up WSSM if at all possible to buy in cal.
Trust me on this, it's a lot of work.

Not that much work-- 243wssm is a pass through the 25 die, trim to square.... the 223wssm is a pass over a 6mm expander, then a pass through your 25 wssm die, trim to square. The shoulder is a few degrees different on the 25wssm but it gets pushed back when you run 'em through your 25wssm die. :) Just remember to lube your necks before you neck up.

I'd look at letting go of a bit too, but all of my brass is loaded at present. I was worried that this cal. would be a flash in the pan so I bought enough brass to shoot the rifle out back in '06 when I bought the rifle. I've been shooting mostly range pick-ups in all three headstamps to save my brass though.
 
The work I'm referring to is in donut mitigation in grossly over-thick cases(~20thou+).
To do what you're talking about means turning onto shoulders, then deep annealing, upsizing, then several fire-formings/sizing cycles to reach the point of Win reloading 25wssm brass out of the bag.
Or, you could anneal, upsize, fireform, ,ream out the donut, and size cycle to re-harden necks.

I take 25wssm to 26wssm. But if I shot 25wssm, I would just buy 25wssm brass. Maybe not right now, but eventually.
I may have a bunch of 223 or 243 wssm brass, if you really want to go through all the hassle to change it. I'll look

So 243 WSSM brass will run through my die and all I would have to do is trim and resize?

I've done up a few boxes and never had any trouble with donuts. I'm using regular redding dies. Maybe I just got lucky but I didn't have to ream or anything.

From the 50 rounder of new 243wssm brass that I did up a few years back, yes. Mike brings up a valid point though that you may have trouble with the thick brass, but I didn't. Your mileage may vary and I would be prepared to ream the brass if it develops a donut.

I have a caliper on a (243wssm reform to 25wssm) round right now and it's .295" at the top of the neck and .296" at the bottom with a 100 grain sierra in the neck. Another measures .296" from top to bottom- also with a 100 grain sierra.There's enough slop in the chamber to wash .001" out. Max. spec in the hornady book is .299 for neck dimension. These brass have been fired and trimmed a couple of times and I'm not sure if they are at the same firing count; likely not as they are in a mixed headstamp box--had a few neck cracks with 25's and filled the box with re-forms. That box is full of sierra 100 gr. pro hunters at 3300 fps with 52.0 gr. Superformance under it lit with a 210. Usually I let the rifle loaf at 3150 with a 100 (or 2850 with a 120), but she screams with that stuff and still holds moa.

It might actually thin the necks out a bit with the necking down. The softer bullets darn near deform stuffing 25wssm brass.
 
I thought I read that you can resize any wssm cartridge to 25wssm. Does that mean that I can resize the 270wssm to the 25wssm or the 243 wssm to the 25 wssm? If this is possible which is the best way to go. I currently have a 270 wssm also, so if this can be down sized [ neck ] to fit the 25 it would be easier on me. Please let me know what the deal is. If I cannot solve the shortage problem I might just sell my 25wssm and 100 rounds and go to a weatherby 257,
 
There is no 270WSSM
WSSM and WSM are different cartridge lines...
Sorry about that, but the discussion on the 243 wssm and the 25 wssm, can the 243 be use to make the 25 wssm without major efforts or problems? As usual I am looking for 25wssm loaded or cases for sale.

If you have spare .223 WSSM brass, I might be your man. A buddy has one, and he doesn't like it, so he said he'd sell it to me cheap. So, I might need some brass if the OP doesn't get it.
