I shoot a lot of the 69 gr SMK's,they are a great shooting bullet. The only moly coated bullets I've ever shot are 75 gr Hornady BTHP Match and A-Max's,and IMO,the moly coating doesn't really do much of anything better than the standard copper jacket bullets.
The moly coating is also a real pain to clean out of some barrels.
In all of my chronograph testing,the moly coated bullets were actually slower than a non-moly coated bullet shooting the same powder charge out of every rifle I've shot them out of.
Unless the moly coated bullets are all you can find,I'd just stick with non-coated bullets.
