To home load it cost around 100/1000. I started loading my own to get subsonic game loads for my Hushpower. However when i got trhe machine it came with powder for about 4000 rounds, primers for 400, shot for 500. and wads the same.
The cases last for between 2 and 6 reloads, gamebore blue dimond are one of the best cases.
For most types of shooting it costs more to load your own, and you hace all the hassel. ocasionaly I get duff ones where the end of the cartridge is slightly belled or the base has not resized properly, these jam!
