I had 2 of these 64s with the Cooey Winchester brands. Accurate and reliable if kept clean and very lightly lubed. Easy to clean after you get the hang of it. My only issue is the pot metal magazine and is the only reason I sold one and gave the other to a buddy. I wonder why Savage did not mod the 64 to use the reliable MKII bolt action 10 round mags.
Both started as Lakefield designs, so it's also a good question why the previous manufacturers didn't make this adjustment as well.
