No experience with the 22-250 but I'll say that I've great success in reloading reduced loads both 223 and 30-30 with Blue dot powder. Blue dot generally burns up in 16" of barrel and therefore doesn't produce much flash or "bang." I get real low SD"s with it too. That said, my use has been to produce loads that are in the 1500-2000 fps range with lighter pills. That may/may not suit your friend's needs.
