You have to shop around. americanreloadingDOTcom, everglades ammo and a few others carry the .311 bullets for a good price, when available. I'm debating what to do with the x39 components i have sitting here. iirc 300+ pcs of new brass, .311 bullets, dies etc. It's one of those do i off them, or keep. Instead of saying 6 months down the road. Should have kept that x399 stuff.
But i still have unopened spam cans collecting dust.
