I have a bunch of 110 grain .308 Z-Max bullets and some IMR Trailboss so I loaded up one round to test out. I just threw 5.0 grain in the case, which is .1 grain above minimum. I did not crimp the bullet. I shot it into a brush pile and it was pretty quiet, but there was not enough umph to eject the case. Hodgdon says that I can go up to 6.2 grains and with a crimp I think it will eject.
This is going to be fun.
