Any thoughts or experience with resizing brass to a larger caliber within the cartridge family?

I have read where resizing 300 PRC to 375 Ruger is doable. It seems a two step process is suggested, first upsizing to 338 and then to 375.

With 375 Ruger brass being scarce, thought this might be an option for folks needing brass.

The outfitter I recently hunted with in Montana has a large amount of once fired 300 PRC brass (approximately 50 boxes) and will sell any or all for 50 cents per case, plus shipping.

I would think it could be done. I did 308 Winchester to 358 with one pass through a 358 reloading die. I occasionally did get a split neck after firing.
 
You might consider just buying some factory ammo and reloading it after you shoot.
 
My guess is it will come out short. I don’t know what 375 ruger brass is running now, or if you can find it. But I would rather have it.
 
I just rum 300WSM through the 35 Sambar reloading dies. A two step to 375 should work ok. Yes the case will be a little shorter but that just save trimming to length for a lot of shooting.

Good morning. I see that you had a Sauer 202 for sale for $3,000. Did you sell it at that price?
I have one for sale as well. I listed it (on here ) at $3,000 as well. Is the price high, low or right where it should be?

Thanks. Alex. [redacted] in case you want to call me to discuss further. I appreciate your time help and support.

Dave, I could use both of them if still available. I just picked up a new .22 mag and a .22 pump that they would be perfect on.
