I just finished settling in on a 300 win mag load as I had a really accurate 178 grain ELD-X load but after losing a deer with a .270 because of a frangible SST bullet I've switch over to either Accubonds or Federal Trophy Boned for my large animal guns or at a minimum a soft point bullet. Also, if you are interested in using Nikon BDC large game scopes they are essentially setup for 3000fps bullets so I use a 180 grain, at full load which usually does not work for the most accuracy but did in this case, and yardages are pretty close to make the gun quite easy to figure where to shoot after zero sight in at 200yds, then easy range shooting for farther shots. But, if going for longer ranges than say 300yds, get to a range and do some longer shooting to verify scope and where it hits.
