Trouble Powder Coating Help
Hey fellas, so I tried PC my first batch of 9mm and 38spl bullets yesterday. I can say I was not please at all with the results. My method is as follows, I use Eastwood Ford light blue pc is a #5 container. I add the bullets and shake them for a few minutes until the bullets are covered. Then screen to remove access powder and pre-heat the oven to 275 degrees and bake for 15 minutes. While the bullets came out looking OK the real trouble came when I went to size them. Sizing the 9mm bullets using a lee push through sizing die it removed the PC from the driving bands. This also happened to the 38spl bullets aswell. Tried the smash test and the PC flaked off in spots. The 9mm drop at .357 and the 38spl drop at .359. My sizing dies for the 9mm is .356 and .358 for the 38spl. The 38spl mics at .362-.363 with PC applied, I didn’t measure the 9mm before I put them they the die. Can anyone find a fault in my process? I’m going to have to remelt all the boolits and recast to try again. I did add alittle lee sizing lube in a container an swished the boolits around for a bit and it did help some but I am still not satisfied with the results.
