I have some new Hornady brass, figured I might as well load a few with Trail Boss.
Measured the suggested minimum of 6.8gr for a 150gr bullet and it almost filled the case up.

Rechecked rezeroed everything and still came up too full to install the bullet unless I wanted to compress the the donuts.
That's supposed to be a no-no.

Just for the fun of it I filled the case up to the top, wiped it off level and measured the load.
7.7 grains

Hodgdon has a suggested maximum load of 7.8gr listed.



Just where is the rest of the powder supposed to go?


How much does your case hold?
