I ordered some from Georgia-Arms about the middle of last year and haven't heard from them still. Since their price was reasonable, I thought I'd start with their loaded ammo and reload from the empties. I think the Gold Dot bullets pretty much disappeared and they just haven't been able to get any.
I've moved on and now have 300 new brass and am about to order some bullets from Missouri Bullet Co.
You might want to give Georgia Arms a call and see if they expect to get the components any time soon.
I've had good luck with them on other orders. Haven't been able to find either Gold Dot or Hornady XTP in .410 anywhere and apparently they can't either. I think the bullet manufacturers are so busy selling all they can make of the more common calibers that they aren't going to spend production time on one that won't move so fast.
