I really don't know if I'm going to go through with this, but it does intrigue me...

I've enjoyed my 7.62x39 model 10 immensely, but can't help but think how much better a hunting and target rifle it might be if it were necked down to take 7mm bullets.

The bonus to me is that I could use the same bullets in both my 7x57 and this 7x39

I have a donor short action on the way soon. So how would I proceed with building, and loading for a 7x39 wildcat?

I presume I'd need to contact a barrel maker who would build the barrel. Would I use 7x62x39 go/no-go gauges for the headspacing?

I guess I'd need to have a 7x39 FL sizing die built as well.

Is this more work than I want to get into, or is it a relatively small project?
