My new rifle will have a Varmint contour barrel at 30" which I'm sure will make it front heavy. So, I keep reading that a rifle that is balanced will "ride" better on the bags. With the rifle completely assembled, where do you hold it to find the balance? I know you can move you hand to different places on the stock and eventually the rifle will balance out. Hopefully, what I hope to find is the definitive place to hold the stock.
