.375 Winchester brass

What I want to know about Starline 375 brass, is it just elongated
30/30 brass or is it true 375w brass? About 3 yrs ago we had to
blow out 30/30s because 375 brass was almost impossible to get.
At shows they had ?x brass at $2@. The blown out 30/30 comes
up a little short of specs. Still we didn't load them to 375w, only
38/55 loads. We didn't feel 30/30 cases would take full power
jacketed 375 loads. I have seen articles where there was case separations using blown out 30/30s with 375 loads. If Starline is
not true 375 brass there's no purpose to buy it. Anybody know
the skinny on this brass?
 
I was at a Cowboy Action match about 10 years ago. A man of about 75 and his 50 year old son were using one of the 1970's era commemorative Winchesters in 38-55 for Speed Rifle matches, I was on the crew that picks the brass up for the shooter. His brass was hideous! I ask him about it and he told me that 38-55 was an obsolete round and the only way to get brass was to use 375 Winchester brass and neck turn the whole length of the brass so it would fit in the loading dies.

I told him his info was a little off! Starline made two lengths of 38-55 and Winchester still makes limited runs of that brass also. I had (at that time) about 350 rounds of Winchester and 250 of Starline "short" brass (same length as current Winchester). He was shocked and almost in tears. He looked at me and asked, "Do you have any idea how long I spent hand turning 200 cases full length?" I politely shook my head. I didn't have the heart to tell him, I have a power neck turning tool that is quick and does a professional looking job.

Now we know where all the 375 brass went. I keep 200 for my Contender and sell all the rest I find.

I own a Winchester 375 and if you ever find Brass or ammo...................

Buy all you can, since the ammo as mentioned is not made that often.

A good short range deer rifle in semi-brush country, one reason it was made.
 
I would guess Cowboy matches are shot with case at relatively LV. I wonder why the 38/55 shooters didn't just blow out 30/30s? They will be short but would make liittle difference with those type of loads.
I think if I get hold of a Starline 375w brass I'm going to split it long ways
to chech out web and measure case walls. I have no idea of set up and the
retooling process in brass drawing. The runs of 375w always sell out quick.
Are the companies afraid they are going to sell to many? You would think it would be more profitable to run surplus while they are set up. From my experience with 375w owners the companies could sell at least twice their
limited runs. Owners are into hording life supplies and others buying them
up to scalp at shows. I have several hundred new Win brass and same in
1x. Guys get mad because I won't sell them some. I got lucky but have as
much as $1@ in some of them.
 
I don't have any Starline .375 Winchester brass, but I do have Winchester brass in both .375W and .30-30. I can report that the difference in weight is only 7 grains in favor of the .375W.

Which is negligible. As all those rounds headspace on the rim, the cartridge base is fully contained inside the chamber, so the risk of a blowout from a re-formed .30-30 case using any standard load does not exist.
 
My 375w / 38-55 dies are Pacifics and are marked that way. I don't see the reason that 375w brass would have to be lathe turned to use in 38/55 dies. Also it's well known that a 30/30 could be jacked up considerably if not for its weak point the case
head. Guys were.getting perforations and separations with blown out 30/30 brass loaded with full power 375loads with jacketed bullets.
