Necking 300 H&H brass to 375

[Wyatt Smith]

Like many of you, I bought the 375 brass at Clark armory that turned out to 300 brass.
I decided to do an experiment. I ran them through my 338 sizing die then my 375. Loaded a minimum charge of H4895 then fired.
As was expected the necks were way short and a little thin, but it would work in pinch. Luckily I am not in pinch so this was just for fun.

You can see I have a 375 sized case and a cartridge in the pictures for comparison.

I like it! Seat to the cannelure. A little more freebore is good anyway. Do you have a photo of the .338-.300 H and H?

 

[Wyatt Smith]

No I didn’t CEH they looked very similar to the sized cases I showed prior to firing.
I am going to leave them alone in case I stumble into a good deal on a 300H&H

Good choice. You'll be able to eventually find a good .300 H and H to fit your needs.

I don’t know if the word “need” is acceptable as I have a 30-06, but it’s nice to have the option. Same reason I bought some of the cheap 7x64 brass.

So true about "need". But when you find any brass (let alone Norma brass at a great price), in a cartridge you may be interested in sometime in the future, it would be foolish not to buy it. If you decide not to pursue it, then you can sell the brass.

@Wyatt Smith
You can always sell the 06 to finance the 300 and end up with a far better caliber.
How is the 25 coming on. I'm still waiting for your write up. We need to convert more to the great 25 as nd it's benefits.

I love my 30-06 Bob. The 25 is coming slower than I would like. I will start the write up this afternoon.
