Re: What's wrong with Moly coated bullet ?
Hmmm..... Think I'll throw in my .02 here.
I've got two rifles that shoot only moly-coated bullets. One is an SPS in .223 and the other a .22-250AI. I'm running the .223 at moderate velocities, don't have 'em handy, and the AI at 3940fps (which will probably go up, I'd like to hit 4100) and they are both using 50gr bullets.
After a Montana trip with somewhere around 800 rounds fired in three days, the .223 cleaned up in five or six patches. Several hundred rounds later, still without cleaning, it's accurate enough to pop sage rats at around 300 yards. Proved it again last weekend.
The .22-250 only has a couple hundred rounds through it, been swabbed with Kroil once just out of curiousity, and kills rockchucks at 500 yards.
I shoot moly because I'd rather shoot then clean. That said, I haven't switched my competition rigs to moly, mostly because they like the load I already have.
That's my experience, and I believe it's typical of most moly shooters.
