I shot that group with some custom Nosler loads, so I have no idea what powder they are using, but it was loaded with their 180 gr Ballistic Tips - their 165 gr Ballistic Tips shoot almost as well in my rifle. I let my barrel cool down after every round to shoot that group and I never shoot more than 3 rounds before letting it cool enough that I can hold the barrel without being burned. Plus, I clean religiously and often - and as often as practical if I'm out on a hunt.
If I can ever find components to reload again, my favorite recipe is straight out of the Nosler Manual and it delivers 3250 fps w/180 gr Speer Ballistic Tips.
