I know it's not vaporware but nobody has them in stock. My next Federal order I will at least put in for them and see what shows up.

1275 FPS rating would be a nice 600lb load if they really pan out. Scroll to the bottom:

Rocky Mountain Reloading shows some pulled 180 grain HST bullets, they would be a great choice for handloaders to stuff into some casings!

I can't wait to see this one I gel.

Intercooler, thanks for posting this. That should be an excellent load. Pricey but excellent.
