There are many misconceptions about molly. Go to a gun show and you see many self proclaimed experts that know very little of which they talk.
I have heard molly will build up and you can't get it out. No, but if you wax your bullets (carnauba is common) it can build up in your bore, and is nearly impossible to get out.
If you want molly out of the bore use JB Bore past. This will take you back to bare metal.
Molly with the same load will actually give you lower velocities because it lowers breach pressure. However, because breach pressure is lowered you can add more powder, and yes then you exceed the velocities possible with non molly bullets.
I don't know about molly changing to acid, I have left rifles uncleaned for months, with no negative effect. I will brush carbon from the bore, but I have many rifles that shoot better after ten to fifteen fowling rounds, and I don't want to shoot a box of shells every time I want accuracy.
The reason you get a better ballistic coefficient is that molly is so slippery that the bullet is not engraved as deeply by the rifling. This isn't good for Barnes X bullets. I have molly coated Barnes X bullets, and when I do accuracy goes out the window. Bullets obdurate slightly when fired. Copper is so hard that they do not do this well and hence have shallow rifling groves on the bullet after they pass out the barrel. I think they loose their accuracy with molly because the engraving is insufficient, or so shallow that the bullet doesn't stabilize.
I ;have a kit from Midway that I use to molly my bullets, and I use molly on most of my bullets.
