Since .300H&H brass is a bit diffucult to find,
at times. Is there any reason to not use .375H&H brass to neck down,other than some work?
Plus one could use RWS or Norma brass.
Also couldn't one restamp the 75 part of 375H&H
with 00 to give it the "correct" headstamp for Africa use? I would think it would work pretty good since a lot of headstamps are kinda hard to read anyway.

I've never done it, but I've heard people swear that what you described is the way to go- if you already have your dies set up to match your chamber you have all the benefits of once-fired brass with virgin brass. Don't know if you have to ream the necks though.

I didn't know how scarce it was getting until I went to look before replying to this. Looks like everyone is out of stock. That's unfortunate. I can't imagine that it'll come back into stock soon. The 300 H&H still has a big following, or what I would think would be big enough. They probably only make it in short runs though. Cabela's still has Winchester brass in the 500 ct. packs. I'll probably snag one of those myself, but it looks like Midway, Grafs, and Midsouth are all sold out or just plain don't stock it. Argh.

Hopefully the Cabela's south of town has some in stock. If they do, I suppose I'll go buy them out some time in the near future.

Allen,

As an avid shooter of both 375 H&H and 300 H&H, I can tell you I've tried what you propose. I've never personally had any success. The 300 die will correctly and easily size down the 375 neck to .308 but, the shoulder then becomes too thick. It is possible, I'm told, to to buzz the shoulder down to the proper size using a "neck turner" tool but, I gave up. If you have any success, let me know. I would love a way to turn my excess 375 brass into 300.

As for unprimed brass - I just bought 100 at LockStock.com - it is a little pricey - 42.50 per 100 but, it's the only place that I know of that has it.

Friends-

Isn't there another alternative in order to make .300 H&H brass? I haven't tried this personally, but couldn't you just run a .300 Weatherby case into a .300 H&H die and presto change-o; out pops out a .300 H&H case?

All you would be doing is putting the shoulder back to it's original position since the .300 H&H was the seminal round for the .300 Weatherby.

Just a thought.

It wont work. Because the Wby is blown out straight it doesn't resize properly in the H&H die.

Just got off the phone with Redding Reloading.
They have a .300 H&H trim and form die. They used it on 2 Fed. .375 H&H cases and it formed them fine, said looked like a factory .300 H&H case.
The engineer said to check neck thickness, might need neck turned depending on brass used.The Fed. brass they tried miked .014.neck thickness. I already planed on neck turning if needed.
Engineer could see no problems with the case.So onward I go!

It might also be worth trying 8mm Rem Mag brass or something made off of it like the 7mm STW. The angled shoulder on those vs. the rounded shoulder on the Wby will probably resize better. Only problem is that I don't know how they'll take to having the die try to slop them down from their normal straight shape? Sounds like you have it nailed down though with that Redding die. I suppose I should get my hands on one of those in the interest of preparedness.

Is 8mm Rem Mag brass still available? It's the same length as .375 only thing is it would be Rem brass..

I think you are going to a lot of unnecessary trouble. Just order your .300 H&H brass from Midway.

Huntington's still has Bell basic H&H brass listed on their website. This would probably be the easiest route for a reforming operation. But if you are looking for better brass Horneber has .300 H&H listed on his website.

Sierra2, you didn't read the rest of this thread. That's the same thing I thought at first, but the problem is it's out of stock almost everywhere. Midway is out, Graf & Sons is out. Cabela's is out except in 500 ct. boxes. One other gentlemen mentioned Lock Stock... and if they have it, they're one of the few at the moment.
