I am planning on buying some bergers and work up a load for my Sako 270WSM and was wondering if the Berger are all they are cracked up to be? The bullet will be used for hunting whitetail in Okla. Our deer size runs from about 80 pound does up to 200 lbs. bucks. And that is on the large size. Usually they are 120 lbs. to 160lbs. I want a bullet that if a deer steps out at 50 yards it will put him or her down but also if the same animal steps out at 600 it will do the same. I plan on using the 150 grainers so it will buck the wind at longer ranges. It has a 1 in 11 twist.
