This fits the Dillon 650 (and probably 750 but not tested).
I have personally have loaded well over 5k rounds with this new cam and it really smooths out the shell plate movement. It is a BIG improvement over the Dillon design.
These are made of 100 percent American made filament. I designed the product and manufacture it here in America.
