I recently picked up some of Nosler's new 200 grain CC's in .323 and compared them to the 200 grain SMK's that I had been using. Significantly cheaper (one of my shooting buddies has a "dealer direct" price deal with Nosler) and very comparable to the SMK's.

Both Nosler and Sierra claim an identical BC of .520
