What are you three favorite deer cartridges, you can even choose your bullet for out to 300 yards? I was thinking about it last night and finally came down to 7mm Mauser (7x57), 6.5-284 and 270WSM The 7x57 would shoot the Nosler Accubond LR 168 grain, the 6.5-284 would shoot the 142 grain Nosler Accubond LR and the 270 WSM would shoot again the Nosler accubond LR in 150 grain. I think all three of these would be effective out to 300 yards. My favorite being the 7x57, killed a truckload with my Ruger No.1 using the Noslers.
