I have a older remington model seven youth with 18" barrel and a 700 mountain rifle. I use the plain rem 140 overlooked haven't had a deer go over 50 yards most drop in their tracks shots from 20 yards to around 250 yards. I hits them right in the shoulder and never recovered a bullet. I killed 6 deer with the 7/08 and dad probably killed 10 or so with it. Never a problem the deer that ran 50 yards dad shot behind should at around 250 yards. The blood trail was really impressive, Easy to fallow. My cousin use Hornady 139 sst factory ammo in his 20" barrel model seven and his son killed 5 or 6 deer and a bear with it with no problem.
