Guys I have been doing this for a while and I have only had 1 batch that the powder would flake off of. The other night I did some 458-193 405 in the same powder I had the trouble with the last time and it flakes off. Well powder is contaminated, or so I thought. Trash that batch of powder and continue on with another bowl I haven’t had issue with. Just to make sure, I ran a test batch of 10 in some different powder they came out great, so I went on about my business and did about 50 last night along with some 429-421 and some 30 cal too. I start sizing them today and several of the 458 the powder flakes off when they go through the sizer. I test some of the 429s no issue at all.
My question is has anyone had this happen? Am I not baking the large boolits long enough? I’m at 400* for 20 minutes that’s from time they go in the preheated oven until the timer quits. Or have I got some contamination in my buckets I put my boolits in to season. The only difference in any of these boolits are what the went in after casting
Im definitely going to wash the next batches out of my bowls that I thought were clean in acetone and for future endeavors I will have dedicated bowls to put my fresh cast boolits in to avoid any cross contamination. The flaking is minimal and I’m going to load them, I may live to regret this decision, but I’ll never know what I can get away with until I try.
I may have just answered my own question but what say you guys.
