You will drop about 25-30 fps for each inch you cut off the barrel. So a 20" barrel would drop your velocity about 100-150fps. So a 24" barrel with give you 50-100 yrds additionl range. I would go with a 24", although the 20" is nice for shooting off-hand and keeps the weight down.
I love the .308, Other cartridges offer ballistic advantages, but I enjoy the challenge of the .308. You have to be more precise with both you elevation and wind adjustments to get good hits at extended range. Adding a .308 will make you a better marksman with all your guns
