Still Molycoating?

What's the latest on molycoating bullets? Is/was it a fad? Is it over?

I got into it about 10-15 years ago, but I quit when a Sako 7mmSTW abruptly lost its accuracy. At that time I was of the opinion it was due to excess moly buildup because I coated bullets, not the barrel. As well, I read that high temperatures at the leade created chemical changes in the moly that were detrimental to the barrel. Another negative was the moly was hygroscopic and that would lead to rust and pitting.

Well, I still have about 500 or so 9mm 115gr HP bullets that I moly'd and I can either load 'em up and fire them or put them in the tumbler for as long as it takes to get most of the moly off.

Any advice?
 
I would just shoot them and clean the barrel.
Heat and pressure is so much lower than rifle loads.
Of course, I have no idea why moly-coating ever was popular--though I do like the coated bullets from Precision Bullets and their coating has some moly in it, but it is not the same as tumbling bullets in MoS2 powder.
 
2600 fps is my moly cut off point. Rifles usually get it, handguns do not.
17HMR is below that, and seems to work without moly.
