Re: Rockchucker too little.??
I just talked to Jake and his problem was, he had his seater die screwed down in the the press to far and was not using the adjuster on top of the die body as it's full potential.
You don't need to screw the seater die down to far in most cases. Screw it down and lock it at a position that allows you to use the FULL potential of the seater rod in the die.
I load the 338/416 and the Tomahawk with the Rockchucker and the seater die has a micrometer on top of it.
Never had a problem at all with the old or new Rockchucker press with those two cartridges.
