I jumped in to load for a friend's new Ruger Hawkeye in .358. The data is not in front of me, but, I went with about 1/2 grain less than max of AA2520, WLR primer, Winchester brass (flash hole deburred, primer pocket uniformed up), and Remington 200 gr Core Lokts. I seated the bullets .015 off the lands. So far, from his less than ideal sighting in, he saw well under 1" groups, repeated a couple times. I'll post back when I get him to do it under some better conditions. But, so far, AA2520 appears to work well.
fwiw

Oh, and the Hawkeye......darn nice rifle, I gotta say.
