To be honest, I have VERY minimal experience with 20" barrels. I can't really say. The best bet is to try it out. I think with the 200SGK, you could still get them up to 2400+ which is not fabulous but would do the job well as long as you limited your range to the point where 1500'/sec is.
The 175 LRX looks like it may be a great alternative for those who can't get the 200's up fast enough. For thinner skinned game, the 168 or 178 AMAXs are tough to beat in the 308.
