I had talk about reload my own primers and ask to put in a different post. This is what works for me. for small and large box primers. I do not know if someone else post this. If they did ok. For me, you take your primer apart and clean out the pocket in it and then take a flat punch to take out the dent in it,I place it on a flat hard steel. then you use cap gun caps that is on the roll .I found Lengens ,I know I maybe did not spell it right . But you get them from Walmart .That is where I got my or on line. They are made in Germany. Check the ones you get because some are made in China and not as good. you also need 4 F black powder or 3 F black powder. You cut one of the caps out and have it fit inside the primer pocket. Before you put it in. you take the Black powder and put enough in to cover the bottom of the primer and then you put the cap over it and then you put the anvil back in, I use a piar of needle nose pliers to press the anvil in, you will know if you put too much powder if the anvil dose not sit flush like it should.then you have your loaded box primer. As for shot gun primers. What I did had someone make up a tool that will fit the primer in and sit flush in it. A round stock of steel will work and make it easy to drill a hole in it to just fit the cone of the primer in it they use a laded hole to drill the hole. then you will have primer not sit flush the rim will be sticking out. that is when you put a groove in it that way the primer sit flush on the stock you use a laded is use for that. then you take the primer and sit it in the tool with the cone face up and take a small punch that will fit in the flash hole of the primer and take it and tap out the anvil and cup out . That is why to drill the hole all the way in your tool you make .You clean the cup out and then take the dent out. Then you take a light round paper that you can use a paper punch and put it in the bottom of the cone of the primer to cover the flash hole ,then you put the anvil in I use needle nose pliers make sure you have the point of the anvil is face you and then you use the same black powder you use on the box primers and you fill up the cone with it ,I made a small scoop out of wood to use to put the powder in the cone also use it for the box primers. then you take a cap you then place it in the cup and then put it on the cone you have the cone sit inside of your tool like it will be loaded in the hull for loading. then to press the cup in the cone you use a C clamp that have a close to flat on the main frame of it . Be careful on this part they do go off on you. I had some did ,just keep it away from your face. You are on your own on all of this. You take the tool with the primer in it with the C clamp you press the cup in the cone till it is flush. then you done . There is one thing I found is that as long the powder in what ever you load is very close to the flash hole in your brass or in your hull you have no problem for it to fire. It is rifle cases that I find there is a delay for the round to go off you get a hang fire. I had seen what Larry Gibson done with use of Dacron to keep the powder close to the flash hole will work for this part. then you have your primers in case of if it comes to that you have a hard time to find primers. Someone on here told me in the past to just use the primers once for reload because the metal will get too thin for being flat out. Maybe someone else posted some of this. But just posted about since I was ask. also with the use of them this way you will need to clean your gun after use because of the black powder use, Unless someone else know more about it, that you do not. I came up with this when primers was start to hard to find and did not know if will run out and did not want to wait the last of my stock is out. It works for me and will do it if my stock is out because of if we go through what we did about 3 to 4 years ago. Now I am ready if need be. I rather use the factory primers. and stock up like I been. But if it come to I will be able to reload my own.I save all my spent primers. There is a thing about shot gun primers. There is some are US size and some are Europe size so keep track of them when you save them and what hulls you got them off of.
