Now that I've picked up my new Ruger Security .380, even though I've yet to get up to the range with it. I'm scouting out Ammoseek for the best deals on a case purchase. CCI Blazer aluminum leads the pack 25-30 deep so far...but by the time you add in shipping, I have to admit, SG is probably the best bet with Magtech brass at $350/1000 case delivered. I've shot plenty of aluminum case Tula and others in .45 ...no issues but Magtech has always been solid and for a few $$$ more, the brass Magtech is worth it.
Will probably order this afternoon.
