if you want to test them one test many use is the smash test. Put one on the anvil part of your vise and smash it with a good sized hammer. I mean SMASH it. If the paint comes off in flakes it wont hold up in your barrel. You might loose a bit on the nose where the hammer smashes it but the distorted bullet should still have consistant color and no bare spots. My guess is you will end up like me. My star sizer hasn't squirted a drop of lube in almost 3 years. Keep in mind though that you changed your bullets and the way they will act. So your load development might be out the door. I get about an equal percentage of loads that stay the same, that accuracy degrades and accuracy improves. So you might need to fine tune your loads for the pc bullets.
