I bought a kit a little while back and have made several hundred of them in .36 and .44 combined. Everything worked well except for putting in the ball. They would always kind of sit on top of the opening and it was a pain. It was made worse when I put some stick glue on the ball first as per instructions. What I did was wrap a piece of blue tape around the post of the former where the "rim" of the cartridge was. It allowed for a wider opening and it worked with the forming block perfectly. Now the ball slips into the cartridge and seats perfectly on the powder. I just got done making 50 cartridges in .36 and only had two of them give me any trouble and even those were easily taken care of. To secure them in the cartridge I used a little elmers glue, the glue stick didn't cooperate for this. This was my solution, your milage may vary. It's a lot more fun to plink with my 1851 and 1858 now.
