When You say "max range", what exactly are you referring to? Max range for deer, elk,varmints, target? With the right bullet (and placement) it will reach out and kill deer size game probably further than most folks can shoot. The .257 Wby is a wonderful cartridge, I own a Vanguard S2 in .257 and get decent accuracy out of all available Weatherby ammo, most being sub moa. Hand loads are fantastic. Ive gotten my groups down to .29 3 shot groups at 100. It is only good with 3 shots at a time tho..... they heat up quickly and POI changes dramatically after the 3rd shot( at least mine does).
