I usually try to do my load development in cooler temps for a couple of reasons. One, hunting takes place during the cooler months, and two, less time spent waiting for the barrel to cool.

As for this adventure, I'm not concerned about hunting, as I won't be hunting with a match bullet. I still haven't decided on what bullet to use for hunting. I've been using the Sierra 65 grain GK, but now that my AR has a 1:7 twist, I'm not limited as much as I was before.

The 75 grain Swift bonded looks nice, as does the 70 grain Barnes TSX and Hornady GMX. The Nosler 64 grain bonded has a rounded nose, but for the shorter ranges the 5.56 will be used for on medium game, I don't think the BC will come into play. But, why not add the extra weight since I can.

Overall, I really enjoy the load development process. It is always really nice to see things come together and get that better than match grade hunting or target round at half the cost.
