You're not kidding. My Buckmark hates me everytime I put bulk Remington in it butit'll gobble up the bulk Federal. But my friend's Savage .22 (exact model escapes me)jams about every 4th or 5th shot with the Federals.
I have Ruger Mark II's and Mark III's and they are the same way. They also seem to like the Winchester ammo. For some reason also thry will not shoot the CCI Stingers if I try to use them they will fire but the empty shell will hang and not eject.
