To fiver Read the message I sent to Brad. I might have misunderstood what you were saying. If you were talking about 2 different powders instead of 2 coats of same powder, some colors just seem to coat better.
I had an interesting talk today with Al at NOE molds. NOE sells molds for bullets that need to be coated and recommends Hi-Tek. I asked him why. He said they have tested P-C &Hi-Tek and could tell no difference in how well they worked. He said he uses Hi-Tek on rifle bullets & P-C on his pistol bullets. He said P-C on some rifle bullet noses will make them too fat to chamber. I thought he would say P-C was better. Weird ain't it!
Brad I'm not trying to sound like I know more about Hi-Tek than others .So if you already know this others might not. Do not mix 20 grams of powder & 100 mil. of acetone unless you are going to coat 40 or more pounds of bullets in the next few weeks. the mix will start to set up & get thick , then it is junk. just remember it is 5 milliliters of acetone to1 gram of powder. I weigh my bullets & mix enough.. to coat them 3 times. at 1 milliliter per pound of bullets for each coat .I have never needed 3 coats but it is better to mix too much than not enough.
they all have the same 100% coating.
smooth and consistent.
i don't just crank the oven to 400, set the timer, and go mow the lawn though.
i'm involved with each step of the cooking process, visually, temp watching, and by time.
i do my batches in three stages of temp and time, the final one is the 400-F one.
it's the curing stage.
