light bulbHello all, I'm trying to help my dad develop a 400 yard - 800 yard whitetail load for a custom chamber 7mm Weatherby. It is a 26" Douglas match bbl (don't know the twist unfortunately, probably 1 in 10) on a Sako action and McMillan stock. NO FREEBORE. I recommended the 180 Berger VLD, but I really don't know. Once I streched my 7mm out too far for 120 Barnes TSX's in light wind, I switched to 338 caliber and 300 grain SMK's for long work. Any advice on bullets and powder would be greatly appreciated.
