22-243

[okietool]

It’s my understanding these are necked down .243 cases.
.243 is necked down 308 , isn’t it?
Is anyone using .308 to make 22-243?

So why isn’t it 22-308

I've made a lot of .243 from .308, but never tried to push it down to .22-243. I'm afraid that would be stretching the limit.

I think trying to neck down a .308 to .22 is a bit much.

Well………308 is the parent case of 22-250 ain’t it? Soooooo…..yeah not sure where this is going.

Savage 25-3000 is the parent case of the .22-250.
The .243 is based on the .308 which has as its parent the 30-06.

I'm sure my dad has made the 22-243 from 308 at some point, I prefer to make mine from 243 though

I have lake city 30-06 match brass that has been necked down to .270.

I made quite a few of my 6.5-06 brass from 270 before I realized why I had to trim so much more on the 270's vs 30-06/25-06...the 270 parent case is actually the 30-03 instead of the 30-06, and are longer in OAL

I “ inherited “ a couple hundred rounds of 30-06 sized into .270 from a former club member that had a class IV is it, to sell reloaded ammo?
Anyway, it definitely shoots good.
Your correct in the parent cartridge of the .270 being the 30-03. I’m so used to using the same shell plate when reloading both that I assumed they both had the same parent cartridge.
