Re: 7mm/08 AI maximum range
Jason, you have more than enough. I've killed two mule deer with my 280 Remington loaded with 150 grain Nosler Ballistic Tip, beyond 600 yards. I pushed those bullet at around 2900 fps. You will be surprised the killing ability of the 7MM caliber, even at those modest velocity. They're my favorite.
To achieve the maximum possible accuracy, all variables must be remove or at least minimize.
