Randy, BUDs carries several firearms that have been discontinued, upgraded, or model tweeked so may not find it on proprietary company websites. Medium heavy probably means medium barrel with no M4 cut in it so it is heavier then a medium barrel with the M4 cut on thr AR type rifles. On Savage bolt action 24" barrels it means heavy barrel with a medium contour where it has a contour from chamber to muzzle not a straight barrel.

You didn’t give enough information for anyone to properly answer your question. But Savage is coming out with a lot of new model rifles and they might not have them on their site anymore. Get the model number and call Savage and ask.
