The rounds your trying to chamber are not loaded correctly. They could have too much OAL. Overall length. Are there marks from the rifling on the nose of the bullet from trying to chamber it? Are these reloads or factory ammo? I suggest you try different ammo and if that solves the problem discard that other ammo.
Being a Savage,Did you take the scope and bases off the action and then reinstall them?
If so,check the base screws,if you put the screws in a different hole,they might be a little long and hitting the locking lug on the bolt.
If you are shooting reloads,your cases could be out of spec or the OAL of the cartridge is too long.
Full length size the brass and make sure the case length is within spec,especially if it is brass fired from another rifle.
Srry I failed to mention above, but this is with factory ammo, and I did try a few different brands, all with same result. Also, the XP3s I tried was from the same box I used last year. Nope, no marks on cartridge after trying to load it.
Is it possible that bedding compound got around the barrel nut, because with the Savage Edge/Axis the recoil lug is bedded right into the stock, the barrel nut is notched, with the threads of the barrel are visible on the bottom????
