Shotgun Slug and Buckshots have nasty tendency to cost much more than most smaller shotsize ammunition. This has driven many shooters to seek cheaper ways to achieve Slugshots by modifying birdshots or using the birdshot cartridge as a base and just changing the shots to slug.
I came up this brilliant idea of a shotgun shell prepper from Youtube user Mountain Storm . All credits to him for the idea.
Shell Prepper will cut the star crimp away leaving a small rim which will act as the crimp to hold the wad and slugshot in place.
