Shooting heavy for caliber bullets that require fast twist barrels tends to create high pressures spikes, sometimes preventing decent velocies. These high pressure and sometimes secondary high pressure spikes keep SD values too high for good long distance accuracy. I played with moly coating when it was first popular but it caused more issues than it ever solved, biggest problem was restoring velocity/accuracy after barrel cleaning. New friction fighter compounds are much easier to work with and accuracy quickly restored by running one patch of friction fighter through barrel sfter cleaning.
Bullets that require friction fighter are 257/155Gr, 264/190Gr, 277/200Gr, 284/225Gr, 308/255Gr, 338/375Gr, 375/450gr.
