IMO, moly is pretty old school, most manuf have moved on, shooters too. Conventional lubed lead bullets won't lead up to 1500fps w/ the right size, lube & alloy. Most leading issues are bullets being too small for the bore. With revolvers, cyl throat dims are as important as bore dims.
With "newer" coatings, the lead bullet is even more viable than it used to be & without the down side of moly coatings infecting the bore. I tried moly rifle bullets when they first came out. Yes they shoot fine, bore wear, maybe a bit less. The bigger issue was accuracy when switching back & forth between moly & non moly. Unless you clean all the moly down to the steel, accuracy was horrible for me in rifles. Maybe not so much in handguns shot at 25yds & less, but moly just has no place in my bores anymore.
