You can also trim 38-55 brass to length. Same argument that Fireball mentions that it is thinner and can't be loaded to 375 Win levels. I've never run a .375 WIn hard enough to notice. I've had two, a Savage 99 I never should have sold and Winchester 94 Big Bore that I just reacquired this afternoon. I'll probably hunt around for some brass but make some out of .30-30 and make up some cast bullet loads that will work just fine.
