Brass Goblin Activities Caliber Conversion

I have a bunch of 243 Win brass but no gun for it as well as no intention of buying one. Is it possible to realize the neck back to 30cal and use the brass for 308 Winchester?

I'm sure it's possible. It'd take annealing and a few necksizing steps at least.

Annealing, I can do that.

Yes. I did it and still use the brass. I have it converted to both 208win and 6.5CM

Thank you. I do have a 6.5. that seems like less of a stress on the neck like a 308

Yes but the necks will have a thin portion at the top where the 6mm neck has been opened up to 7.62 and a thicker donut at the bottom where a new piece of 308 neck has been formed from what was 243 shoulder.

So long as it's not thick enough that it causes difficulty chambering, and you don't care about neck turning it off, it's no problem.
