1st 6ARC loading.

Fyi, in another caliber but still AR frame, I run out of room in the mag well at about 2.350 (this is a rough measure I did last nite about 2 AM, but the length should be somewhere like that), so my practical ultimate limit is probably more like 2.330 for some tolerance. But I won't be doing any 90 gr tgk's at that type of setup.
Roger that on the Howa having more OAL room.
