Check with your local hazardous waste, or landfill, department. There is probably a place to drop it off to be properly disposed of. In my city, there is a group of volunteers who do this on the first Saturday of the month at no charge.

No the e-coat is a electro-static primer. It is very durable just make sure it is scuffed properly before priming or painting.
Oil Based Primer, or any Primer for that matter, typically peels due to the bonding surface being poorly prepared. There are the occasional defective products as well as the dry times that were shortened by top coats, but usually it is the surface at fault. Some metals offer little adhesion, woods must be properly prepared and pre-finished surfaces need to be sanded down to original material for adhesion.

MC-1 primer for asphalt is a common solvent used for roadways and pavements. It is commonly used as a base application.
You can check to see that the primer is properly seated into the primer pocket, the brass is crimped properly and the overall cartridge length is correct. However, you can't accurately measure the powder charge and that's the most important, and potentially dangerous, component in reloaded ammunition.

The primer bulb probably needs to be replaced unless either one of the fuel hoses leading in and out of the primer bulb bracket is clogged. Be sure you mark how each fuel line goes before you remove the bulb so you can replace them correctly. Hmmm.

You didn't mention whether you were using latex or oil based primer and paint, but generally the point of using primer is so that you can paint over it with any form of wall paint. Just read the label on your primer can to make sure it is compatible.
