I bought a Savage MKII GL back in the spring. BTW The GL is because it has a left handed bolt.
I normally shoot Remington Golden Bullets. They come in a 550 pack and are less then $12 from WallyWorld. I tried these in that rifle and had a hard time getting an entire mag to cycle through the rifle. I also keep CCI Mini Mags on hand so I tried these. Same thing happened, feeding was iffy as I cycled the bolt. The CCI definitely worked better than the Remington. Then I picked up a box of Federal in a 550 value pack. WalMart has these at less than $10. These Federals are copper washed I believe, not just plain lead. Well they feed great, no problems what so ever in over 500 rounds.
So the moral to the story is, buy the Federal copper washed in the 550 pack.
I am not buying the Remington Gold Bullets anymore.
As for cleaning it. I generally clean all guns after shooting them, the MkII as well.
It really does not get very dirty using the Federal rounds. I still pull the bolt and wipe the face a little and I also run a patch through the barrel. But really it is not all that dirty even after a couple hundred rounds.
Enjoy shooting it, mine is a lot of fun.
