They are tapered cases, and due to that you can't get carbide dies for them, only steel die sets. I think they made factory brass for them but there were no factory loaded cartridges produced. So you really needed to be a reloader to own and shoot one of these guns. Reeds lists loaded ammo for the 375 but they must be out of stock since I ordered a few boxes weeks ago and haven't heard anything from them.
I think you can cut down 375 Win brass to make cases for the DW.
Anything worth doing is worth doing well.

can't say how many were made my highest sn. is 375MB001110. You can turn down 375 winchester brass or pay dearly for 375sm brass when it shows up on the internet. great shooters with 220 grain flat nose or the 200grain from sierra.

Don't think I have ever seen any info on the amount of 375's made.
Wonder if The Savantist has knowledge of this ?

Photo #2 looks like 375 Winchester cases. They would need to be cut to prpoer length. The first photo looks like .30-.30 cases.

right , but what i'm saying is which one of these as far as the case it's self looks like 375 supermag , the 30-30 or 375 win or you can use both , tapered and non tapered ?

Promad,
You can use both, I have some of each from an aquistion I once made. I have had problems with the thinner .30-.30 brass not holding up to pressures and would recommend avoiding it. Sorry for not understanding the question correctly.

thanks for clearing that up , yea i had heard the 375 win had a thicker case for handling higher pressures, i'm gonna go out on a limb here and you might not be able to answer this but why can't you use 375 win dies for reloading the 375 supermag ?, i'm sure i'm just tired and not realizing why it's not possible .

Grab a reloading manual and look at the diagrams of the case for the 375SM. The taper is very slight but it is there. I think a 375 win crimp die would probablly crush a 375 sm case as it is shorter than a 375 Win. either that or it wouldn't crimp due to being shorter.

This may not help much, but here's a shot of the four SM calibers, with the unloaded .414 being the odd man out in the group.
And no, the 375 Win dies will not work, I tried that idea before I found my SM dies.

I have loaded 375sm with 375win dies but the problem is you cant crimp with them.

That kinda makes them not work in my book.
The 375 Win die set I have, the expander die won't adjust down low enough to expand the SM brass. So that pretty much left mine only good enough to punch primers out, using the sizing die. I didn't get any farther than step one with mine.

No I sure don't have that info. They were originally made for the silhouette shooters, then a few of them were sold on the regular market. Redding still has the die sets, of course they are custom and will cost you. Saw one set just sell on Gunbroker for $160. Unless the gun came with a set of dies, I would factor in $180 to the cost of the gun before I decided if it was a good deal or not.

I cut down a set of LEE 375 Winchester reloading dies to use for my 375 SuperMag. Then I found a set of Redding 375 SuperMag dies at a great price. I like my LEE dies better. Look in the books for the case length for SuperMag, 1.600 or 1.610 and the 375 Winchester. I removed the difference with a Dremel tool and cutting disk. There was something funky in the operation of reloading with these modified dies, but can't remember, nothing that can't be worked out with other dies or tools you already have if you are going to load for a 375 Dan Wesson SuperMag as it probably is not your first adventure into doing it yourself.

Hello, Would 38-55 brass work? Just wondering.

Lee makes a .375 crimp die that works really good. I bought a DW .375 SM last year and have a few hundred IHMSA once fired cases and a bunch of cut down 375 Win cases which I use for all my shooting. Shoots great with the Sierra 200gr when you can find them, have been casting my own 225gr gas check flat nose, still working on an accurate load, getting 4-5" at 100 yards. Would like to cut that in half.
