Savage offers what they put on other rifles.
They offer a sporter, One for standard calibers and one for the magnum guns.
Something in the middle on the 10PC and predator.
A varmint profile.
And the target action guns have a heavier profile.

The some are blued, some are parkerised, and some are stainless. Some are fluted, some are not, and some have a muzzle break, and some are threaded.

On contour numbers you can not go by that because each company's numbers are different. for example a #7 Shillen contour is different than a #7 Krieger contour. Most aftermarket barrel makers offere a contour similar to the Savage factory countours, but they all call them different.
