Hornady 30-30win brass problem

[emp1953]

I have a whole lot of time on my hands, lately. So I've been prepping lots of brass. When I got to priming all my Hornady 30-30win headstamp brass none of the CCI200 primers would even start to go in the primer pocket. They are definitely large rifle primer pockets. I cleaned them out til shiny and still wouldn't start. Took a chamfer tool and chamfered an angle around the edge of the pocket, primers still won't even start to go in. I've primed, with no issues, FC, PPU, WW, RP, LC. Just the hornady's. Has anyone else had any problems like this with hornady 30-30win brass?
