Okay in the picture you can see slight marks on the body by the pen point and bullet tip. That is where pressure point are. This is a loaded round full length sized with the same die. It will not chamber at all. It measures at the base .500 also.
I doubt a "small base" die is going to squish in enough where you point to high up on the case body to ever rid it of the memory that that brass has formed of having been fired in somebody else's apparently much more cavernous chamber, to ever have that brass running well in your chamber.
If you're gonna buy something, buy the ~ $38 Hornady Headspace Gauge Tool which is a comparator body and five bushings with five different size orifices corresponding to the five most common case shoulder datum line diameters (use .420" for 6.5x284) and measure the case head the shoulder datum lengths so you'll know what you're dealing with now, and from now on.
