But i am a long time reader. Ive recently been interested in shooting up to 700 yards but have been stumped on what caliber to build. The biggest game this rifle will ever see is a whitetail deer, and most of the time it will only be targets. However, im trying to find a round that will be relativly flat shooting, yet also not a barrel burner. So far im considering, 25-06, 6.5x55 and a 6.5-06. What can you guys reccomend or tell me? Thanks.
