Have a silly question about corrosive primers

Using corrosive Frankford Arsenal primers in modern cartridges since modern primers are at a premium price. How much of the corrosive agents are destroyed during the burning of the powder? Maybe, there is not a answer to this question but, have to try. I realize the gun needs a good cleaning after a shooting session. Thanks for any info anyone may have.

    As far as I know, none of the corrosive agents are destroyed during firing. To the contrary, they are spread throughout the chamber and barrel. Hence the need for cleaning.

    I have never seen any information like that. The point is, corrosive primers leave a hygroscopic chemical in the bore that readily absorbs moisture. The old rule-of-thumb was to clean your rifle at the end of the day with hot water or GI bore cleaner. There is a lot of info on the internet if you don't have access to some older written material. Good luck.

    The residue is still plenty corrosive even if the priming charge burns completely. It is not like smokeless powder. It does not disappear completely.

    In my opinion the bore should be oiled as soon as it is cool enough after shooting if you cannot clean at the range. It will slow how fast the rust begins.

    Thanks Gets, appreciate your information. I was very suspicious that these would be the answers. Thanks again.
