I've got ADG in .308. It is intentionally made with heavier brass and slightly lower powder capacity than average, that being a tradeoff made to get longer reloading life. For that reason, it will be a little less suitable for 1000 yards with 155-grain Palma bullets than higher case capacities will. The case weights vary just a little, but the internal volume seems to be super consistent. The heads are double-struck to be very hard like LC brass, so these would be a very good choice for the M1A for anyone still using one in service rifle matches.
Made in Kentucky.
Now I just need to acquire some Peterson to do a side-by-side.
