The first thing to decide is why did your bullets become corroded. If they were exposed to moisture and put away damp, the powder could have become damp and the cartridge may not fire. The only problem here would be if you were depending on these cartridges on a hunting trip and you ended missing a great shot because your ammo was defective. I'd sure question why the bullets were corroded. If you feel that the corrosion is from something such as the cartridges being left in a cartridge belt for a long time and being subjected to the chemicals in the leather, I'd very carefully inspect the sides of the cartridges for corrosion pits that would weaken the cartridge case and could cause rupturing in the chamber when fired. The gun is designed to handle such failures and you would not likely be injured but the ruptured cartridge case could become jammed in your chamber and require a lot of work and a possible trip to a gunsmith to get it out. If you determine that the cartridges are safe to shoot, just use a bit of four ought (0000) steel wool to remove the corrosion. That's all that would be needed.
