Yes a convection oven would be a show stopper for me! I don't even have one to cook my pizza in, so I'm not buying one for my boolits.
As stated earlier, I have less than $50 in the whole setup I am using. This includes my $10 toaster oven.
OK last pic for the day.
These are rifle boolits for my 300 AAC. I coated them, and tossed them on their side to bake them. I did not want to try and balance them standing up on the trip to the oven.
The only down side I experienced on this bake, was realizing I should have used a fresh piece of Non-stick foil. The only ridges and imperfections were from the boolits sicking to the powder that had been cured to the foil from previous batches. Other than that, there was not any globing or any imperfections I could see.
I am done with my initial testing for now. I need to cast some fresh slugs and experiment with other variables. (amount of powder, amount of Airsoft BB's, Temp, humidity, etc)
It has been fun. Now time to stuff them in some brass and check function and accuracy!
WORK, WORK, WORK!!

Guns are like parachutes, if your ever in a situation that you need one and you dont have one, you'll probably never need one again.
