For starters the Sako likely has a 1-14 twist so forget anything over 55gr.Some will shoot them most won't unless driven fast.I handloaded 55gr Hornady[old style with canalure] over 24gr of Win 748 in a Sav 340/.222 for Ontario WT's He ran up a string of a dozen deer all with one shot.I wouldn't shoot much past 100 yards taking only double lung/heart or neck shots.Last fall my son dropped a running WT doe at 75 yards [head on] with a centre of the chest hit.Load was a Rem 50gr HP/19gr RE#7 Dead before she hit the ground lights out! My dad also shot 3 pest black bear each with one shot with the first load.The Innuit in our North are still wackin walrus,caribou ,seals,muskox and even polar bear with the triple deuse..............hard to find fault with that.....Harold
