I would say this is not normal, my kid has a savage rifle she shoots f class with we load 215 bergers so hot that lapua brass wont hold a primer after 3 firings and don't have this problem even in 90 degree heat. If it is doing it with factory ammo and its not hornady super performance(Have seen this ammo cause problems) I would think a trip back to Savage may be in order. 2800fps is pretty fast for a 165 out of a 20 inch stick for a .308, I can see the 140's as we get 3000fps with 130 bergers in a 20 inch. I am not saying its not possible but 165 or 168's moving that fast is a pretty stout load. Her 215's are going 2600fps with a 28 inch barrel and 43.4 grains of varget which is hot. .308's don't seem to care that much about barrel length though like other calibers.
