I am looking at rebarreling my winchester model 70 extreme weather 300 win mag. The barrel on it now is just not enough for what I want which is long range shooting/hunting. I have decided on a lilja barrel but I am unsure of which contour to order. I don't want something that is going to be extremely heavy but I want something that is going to keep somewhat cool shooting and work well at longer ranges. If anyone has any pictures or good experience with these input would be much appreciated.
