It depends on what your particular firearm likes. Every firearm is different, what shoots well in mine may have terrible grouping in yours. So try ammo from different manufacturers and see what works best for you.
You should see some good accuracy with 168grain match grade ammo. I see no logic shooting Tula ammo through a rifle designed for precision, leave the Russian ammo for the Russian guns, if you must feed a precision rifle junk ammo, then sell the gun and go buy a lower grade firearm designed to shoot marginally accurate, and show little care.
