george, I'm fairly new to long range shooting myself, but I'll give you my experiences for what its worth. Moly-coated bullets are supposed to reduce your friction in the barrel so you can load them up a little hotter. In the last 2 years I used Berger 210 gr moly VLDs in my 300 Win mag at 1000 yd competitions. Accuracy was enough to place in the top three once in while but not great for bragging. I personally haven't noticed enough of a difference to justify them. Because of the extra process of cleaning moly out of the barrel, you might find that plain bullets will suit you better. Maybe someone else out there has more to add and could enlighten both of us
