Get some decent ammo for the rifle and you will enjoy it a lot more. Several places have 174 gr HPBT ammo for under $20. 203 gr SP ammo is very good but at the moment it is no where to be found. I shot three deer last year with 203 gr SP, it does about the same amount of damage as a 12 ga sabot.
Spam can ammo is worth what you pay for it. The 91/30 is rifled to shoot 180 gr + ammo. The 91/30 likes a long, heavy bullet. The 174 gr HPBT match bullets are very long for their weight and they are semi jacketed so they expand like a pistol bullet.
