Federal bulk pack shoots ok in my experience also....run from the Winchester bulk packs, they are unreliable. Winchester AA run great.
Ive ran about 600 rounds through mine now with Wallmart bulk packs. I shoot Federal though and have not had any cycling issues. I did have a round not fire yesterday on one of the 3GN classifiers, cycled the bolt by hand, kicked out the shell and I inspected it after the stage. It did not have any striker mark on it at all. This is the first time this has happened to me.
Ill be placing an order this week for the 10/22 extra power spring and hope it gets here before the shotgun match this Sunday.
