Last night I stopped by my awesome local gun store and I could not have timed it better. The clerk was stocking the shelves with a fresh order from that day. Long story made short, I got 8lbs of H110 and 500 of the Sierra Match King 30cal/.308 bullets. When I got home I checked out my Sierra reloading manual and noticed that H110 was used for subsonic .300 BO cartridges in all of the grain weights for 30cal bullets, except for the 240gr. I have 8 lbs of H110, and I would like to use it. There has to be a good reason why Sierra decided not to list it in their book. Has anyone pushed a heavy bullet with H110?
