Really, just based on energy deposit from the heavy, rapidly expanding bullets. If you vouch for the 250-286gr for whitetail, I'm good with that. I have some of each, so once I scope the rifle, I'll check out the POA/POI of each bullet. I'd guess that within 200 yards, drop would differ very little between a 232 Norma and a 286 Woodleigh, at least as far as a deer is concerned.
