OK.
I order the 5.7x28FN from Ed's Contenders. I should be getting it sometime in the middle of next week. I can't wait to start reloading for it. I would live to hear advice from others that already own one and have had some time to experiment with it. The powders I have at hand:
Blue Dot, 2400, Lit'lGun, H110, H4198, Bullseye, Unique, Red Dot..
