One way to test your ammo is the nail test. You break down the bullet, dump out the powder (the power is not corrosive) and use just a primed case. Start a nail into a 2x4 with a head that is less than 30 cal. Slide the primed case over the nail and while in a safe place to do it fire off the primer onto the nail. Let it sit for a couple days, you will know if your primer is corrosive or not.
