Making 300 Blackout Brass

[Bradmartin78]

Couple years ago there was a list of 223 brass to use for 300 Blackout. I remember Lake City, but otherwise I don’t remember. Is ICC any good? Thanks

Thank you, sir. That’s exactly what I was looking for.

Most need neck turning, case wall thickness varies.

Its pretty easy using one of the tiny chop saws from Harbor Freight. Get the jig off of ebay. It makes it super easy.

Cut it at the base of the shoulder, run it through the resizing die, trim the case. Its that easy.

keep in mind if you use LC brass you have to ream the primer pockets. But it’s great brass for 300.

Widden makes a 300 Blackout trim die for the Dillon trimmer. It’s less than half the price of the Dillon die. It goes quickly.
I have a new Squirrel Daddy jig if anyone is looking for one.

I went with the Little Crow Gunworks World's Finest Cutter. World's Finest? I dunno, but it works pretty good!

Built a neck annealer out of a microwave turntable motor, a 6" cake pan, and a propane torch... Also, seems to work pretty good on the cheap. Picture to follow...

That is the jig I have.

I am using the Lee case length trimmer.

It also isn't carbide and wont last nearly as long. Better than the GSI dies which wear out after a barrel, hopefully their heat treat is better these days.

Dillons carbide trim dies work very well, they are worth the price.

For a side project to help out a friend it’ll do the job just fine. I don’t plan on doing more than a couple thousand over the next few months.

I like this. Been watching videos all day on the different shapes, sizes and styles of annealers others have made and use. This is just right for my simple mind Thanks for posting.
