Everyone make your run on "safe lite" matches now before they become the next toilet paper.Well this is for you spent primer rebuilders!!! I have SUCCESSFULLY rebuilt primers. Pry out the anvil, use a punch to re- flatten the cup. Now soak "safe lite" matches in alcohol and cut the white tip off. Make a slurry of the white tips and pack it into the primer cups. Let it dry and re- install the anvil. Bang! Smells funny, but it does work, and accuracy didn't change much in the 45 ACP loads i tried.
