I work with a guy that has a box or 2 he is willing to part with. I will check with him, meanwhile give me your # and I will have him contact you.

You might try and find .38-55 brass, from what I can find, the two are very similar, except the .38-55 brass will need to be trimmed about .065" or so, as it is actually longer than the .375 brass.
Also, it looks like the .375 case mouth outside diameter is .400" compared to .392 for the .38-55.
I think I'd try.38-55 first, before trying to size up .30-30 brass.
.30-30 brass is about .020" longer than .375, and is also about .004" larger in diameter measured right above the rim. .38-55 brass is within .0007" of .375 brass.
Natchez seems to have .38-55 brass in stock for around $50 per hundred....
Couldn't seem to find .375 nor .38-55 at Midway, Brownells,nor Brunos.
I seem to remember that Winchester was having problems with people firing .375's in old .38-55's with damage resulting....

From doing some searching, these folks might have some .375 brass, converted from .30-30:http://www.eabco.com/brass01.html

It seems that .38-55 brass is thinner in the web than .30-30, and .30-30 is thinner than .375, so any conversions should be loaded to lower pressures than full-house .375 loads.

One method to fireform .30-30 brass was to use about 8 grains of unique, with a small wad of toilet paper over the powder, then fill the case up with Cream of Wheat up to the top, and use another small wad of toilet paper to hold the CoW in, then fire the rifle held vertically.

This should fireform it nicely, according to what I have read.

Fowelkiller:

There is an article in the latest Handloader magazine about loading the .375 Win., along with using .38-55 brass, loads, powders, bullets etc.

Good article, and well worth purchasing the magazine eiter at a store, or ordering a copy from Handloader...
