1st 6ARC loading.

[300BLK]

Hornady also lists a 80gr. GMX with a load range of 24.3gr - 28.7gr so I'm about in the middle of that.

Biggest issue will be if the actually chamber at the length I have them at.

80gr cup and core should make less pressure than the 80gr GMX.

I was trying to find the rifling in my Faxon barrel yesterday.  Its no problem with the Hornady and Speer bullets I have, but the 90gr Sierra Tipped Game King is a whole different story.
