there are several sierra 220 pro-hunter round nose loads listed at
http://www.reloadersnest.com/frontpa...?CaliberID=135
the only round nose bullets I have tried in 220 grain are the Hawk (8.5grains H110, 1.665 measured at the ogive, Federal 205 primer, 1080fps) pretty soft bullet...accuracy was ok, not near as good as the matchkings or gamekings...
