TIA- I have an old Rock Chucker press probably 25-30 years old with the setup to feed primers. There are two allen screws that hold the primer tube mounting bracket to the press. I don't have the two screws and before I run out to the hardware store I figured I take a shot at asking here if anyone knows the screw size? It's a long shot but there are some pretty knowledgeable re-loaders here. Once again thanks!
