I'm trying to strike a compromise between barrel contour and weight. I have built 3 rifles with light varmint contour barrels that are 24-26" and weigh approximately 3.5#. I like that contour but still end up with a 10# gun at the end of the day. My next build is strictly a hunter. Likely a .243 and I need it to be lighter. Other than weight, what do I give up by going with a sporter contour?
