They look really good to me.
Actually, that is the kind of coating recommended to me by a Phd Proffessor of Polymer Physics years ago. I asked what I needed in PC build out to form a polymer jacket that would withstand the full power torque spinup of 50K pounds of chamber pressure of a 30/06. He estimated approximately 3 mills.
I double coat my rifle bullets doing a "partial cure" first coat then "full cure" second coat. This method allows the two coats to bond as one. A heavier coat can also be achieved by preheating the bullets before tumbling.
On Hollow Points such as these I preheat to 300+ degrees and spray on my bed of nails.
I think I’m going to stop bouncing off my excess powder and leave a thick build up for my rifle boolits from now on. Just makes it hard to seat GCs as the PC “puddles” or put a “ring” of PC at the base when melting and flowing down when I stand them up.
It seams lately I get a thinner coating. I think it’s because I’m coating in the spring and summer VS the drier winter months.
Try COLD water dropping after PC cook. 9mm is high pressure and needs harder alloy. You may need to keep the loads separated by size. Red Dot is very fast, making size problem worse. Try 231 or unique.
Whatever!
