I wanted to link to a thread I started about recreating the Russian 9x39 ammunition here with a well-appointed reloading bench.
In short, I think it can be done. All this talk of 6.5 Grendel builds has my mind working overtime on building this cartridge. I do honestly believe it can be done and after talking to a few people it doesn't seem to bad - assuming I don't mind the reloading part of it.
I'm open to all input...
