What are you asking for another for 100 rounds of brads for the 223 wssm because I am short on brass and I don't know where to find moreRob, I've had good luck with Varget for the lighter bullets and H4831SC and RL-22 with the heavy bullets. Your 1:12" twist won't spin much over a 60gr, so I'd say stick with Varget & maybe a 55gr Gameking or NBT. H414 would be worth a try, too...
Also, I've got PLENTY of brass, so if'n ya need an extra hundred, lemme know...
