I had a guy come at me the other day and insist that the Co Ax press was the most accurate press out there and was superior to mine in every way. Mine couldn't be as accurate because the die holder didn't float.
I asked him to tell me why and he could only stutter.
I informed him that if the holes were aligned properly the small amount of clearance in the Shell Holder would make up for any misalignment between the die and the cartridge. I then told him that the relationship between the guide rods on my tool and the Die or Shell Holder holes was +/-.001 and done on a high dollar CNC machine which repeats nearly perfectly every time. The parts are also inspected closely by me when assembled and everything is checked for alignment after assembly.
He was pretty much shut down at that point, but then I made it clear that my tool would do something that a Co-Ax couldn't do,, And that is,,, "Stand up by itself!" Mine also fits in a nice little case and you can have your entire Reloading System contained in a Medium Tool Bag available at any Big Box Store for $15.
He is now impressed with his new BPM Hand Press which he purchased from me on the spot.
Funny how people act after a little education.
