Fer Pete's Sake jo, how is someone else's rifle particulars going do anything for your rifle? Variation's in chamber/throat/barrels will all make a difference. Load up some 162's to kiss the lands in YOUR rifle....it don't make a lick of difference what they measure in someone elses rifle. Work up and poke them through the chrony looking for pressure and see what YOU get in YOUR rifle. A speed and a powder was alread mention, what else do you need? Poll 7 guys on the length of their rifle's throat and you'll likely get 7 different anwsers....give or take.
