What are the good and bad .22 LRs for a MArk II?

remington brass plated hps (525 value pack)?
Federal 550s form wal-mart?

thoughts?

I just ran the federal 550s and Remington 525 value packs through my MKII, no problems at a all. The I tried Remington subs sonics and I expereinced two misfores, but the cycled reliably.

I prefer the Federals. They seem cleaner.
