Don't go deeper then .004" My best shooting barrels have a .003" deep groove.
With the 17 rot a elliptical will work fine. Rick at KAL up in Canada made a .432" X 1.460" long that drops out at 504 gr that is the best shooting bullet for my 1/17 ROT Krieger barrel. I use it for the .44-75 Ballard and the .44-100 Rem st also in the 19 rot .44-90 BN Shiloh.
Where can I find a barrel like that. Even the badger barrels from Buffalo Arms are .005
