Standard Dillon Toolheads

CNC machining gives the toolhead’s contact surfaces and threaded die positions the proper relative alignments required to mount dies in progressive loaders with maximum precision.

Anyone who wants to use their progressive press to load to the highest standards needs a CNC Machined Toolhead for the ultimate in accuracy! Why won’t your factory toolhead do this? Factory toolheads are designed to be mass-produced to hit a competitive price point in the reloading press market. Consequently, factory toolheads are made as a large batch of castings with little specific attention paid to surface alignment and finishing.

Whidden Gunworks is pleased to offer CNC Machined Toolheads for the Dillon 550 and Dillon 650/750 loaders!

Floating Dillon Toolheads

The Whidden Gunworks Floating Toolhead utilizes precision locking rings that are purposely designed to fit over a pin in the top of the Toolhead, although secure this allows the sizer and seater die to float. This unrestricted movement allows the die to center itself over the cartridge case for the best possible alignment thus yielding consistent and concentric ammunition.

Concentricity refers to how straight the bullet is on top of the loaded round. A bullet that is straight will enter the rifling in the barrel that way which will result is superior accuracy.

The Floating Die Toolhead is available for two different Dillon Presses. The Dillon 550 and 650/750.  The Floating Die Toolhead includes the Toolhead and two (2) Lock Rings.

Please note: Our Click Adjustable Sizing Die will not work with the Whidden Gunworks Dillon 550 or 650/750 Floating Toolhead.

Will this system really load ammo good enough for 1000 yard shooting?

“Absolutely. I have been loading all of my competitive ammo, for practice and matches, on a 650 with a floating die toolhead since 2003. The ammo that I will be taking to the World Palma Team Championships and World Long Range Individual Championships will be loaded on this machine. You have my personal guarantee that this will load the best ammo your dies can produce. If you’re not 100% satisfied, send it back for a full refund.”
