It might help us to know what caliber that you are looking for! If you are looking for a stainless varmint contour barrel, I am only aware of: .204, .223, .22-250, and .308 (These are Cabela's exclusive).
At this point, it may be worth your while to look into an aftermarket barrel and to sell the sporter barrel! There is lots of information on here regarding barrels. Some prefer one and others despise it. It is variable depending on what type of shooting you will be doing, bullets you may be launching, and goals of the particular rifle.
