Coated about 500 401-175-TC's starting at about 6AM while it was still cool and the humidity may have been up a bit. I haven't been PC'ing for several months. The HF red usually sticks nice and thick with ASBBDT but these boolits have been sitting in the garage for about 6 months and the coverage was thin at best. I tried pre-baking a batch and the coverage was still poor:
You can see the speckled texture on the face of the bullet and the drive bands
HOWEVER
After I put them through the sizer, the drive bands were smooth and flawless. Look at the reflection of the light on the sized portion. That's all that matters when sealing off the gases and preventing gas cutting as the boolit goes down the barrel. Of course that also assumes the barrel grooves are narrower than the drive bands (mine are by about 0.5 to 1.0 mils).
Will it win any beauty contests or be mistaken for commercial ammo? No, but no one will notice at 1000 fps out of my M&P40 and the barrel will stay clean. I've had this happen before and the bullets performed just fine. It is certainly not worth it to do a second coat or melt them down just for aesthetics.
If you can see that the polymer has fully coated the bullet, run a few through the sizer to see if you actually have full coverage of the powder coat even if the color is not uniform.
