Welcome dad,

I was looking into the same rifle a week or so ago and couldnt find much. I ended up buying a used stevens 62 for cheap. I can not see a difference between it and the savage 64. In fact I bought a wood stock for a 64 and it fit perfectly.
I actually bought the rifle for my son so I could recaim my Marlin he has cabbaged on to but, after playing with the stevens I decided he could hang on the Marlin.

Mine has fed, fired and ejected everything flawlessly so far, including the FED 550's. Only put around 500 rnds down it.
