takes place . these procedures are used to achieve a specific hardness . this is done to increase their resistance to extraordinary stresses . after the cases are drawn to maximum length the blank cylindricals are then headed . forming the rim primer pocked and headstamp in one 55 ton stroke . jamison international sometimes makes specialty headstamps labeled for custom orders . next the rims
