Hello Softpoint, I have a Savage 170 like yours and as a matter of fact shot it today. My 170 is a good shooter, and has had no feeding issues, even with Hornady LeveRevelution shells. I would check to see if the screws holding the for-end to the barrel are tight and the tube straight. You might also have crud in the carrier, an easy fix, as the trigger group can be accessed by one screw and a pin. Just be careful when you pop the pin out, it might bend. I have taken mine apart, and it is not difficult kind of like a pump shotgun (Which is what they used to make this rifle). The other thing when loading the tube magazine push the round fully so it is locked by the shell stop, don't just push it in and pull your finger out.
