I have some Fed 209 primers but can't find any recipes for them in my Lyman Shotshell Reloading Manual. There are several recipes that use Fed 209A. Is the Fed 209 primer useable on recipes that call for Fed 209A primers?

Also, I purchased 500 once fired Remington Hulls (20 gauge) from Midway that want fit into my shotgun. All my reloaded AA 20 gauge hulls work fine. Any ideas about this?

Thanks.
