Never had a stuck case with it. in 15 years. For big batches (a couple hundred pieces) Zip Lock gallon bag is the way to go for sure. But yeah, you got to be patient. I spray them, roll them around and spray again and roll a second time really good. Open the bag and go do something else. I tumble them loaded to clean.That is what a majority of people who have stuck case issues have done wrong so don't feel bad. If the directions on the can are followed it doesn't happen.
20-30 rds for load development I do imperial wax. I just hate wax wiping the wax off one by one.
