Shooting Technology Funnel 9X21 Per powder measure Dillon

This funnel was created to improve the flaring required for ball insertion before the ball insertion phase.

Rather than preserving the case from the hourglass effect, the flaring of this funnel allows for the integrity of the bullet caliber diameter to be safeguarded (particularly for those such as bare, painted and copper-plated lead), avoiding the narrowing of their side during the bullet insertion phase.

It also allows for excellent axial alignment of the bullet/case (in progressive presses, no more bullets resting on the case that lose coaxiality with the latter during the rotation of the shell plate). With this type of funnel, the use of the 4th Die (Factory Crimp) is mandatory and the insertion and crimping phase with the same Die is strongly discouraged except for armored nose cones.

The end result is a complete cartridge, which will certainly improve shooting accuracy and trajectory stability of the bullets.
