The Federal 525s are my box of choice to feed my Marlin 60. Never fail to feed, fire or eject and the accuracy is excellent; 14 rounds through a loony at 50.
Winchesters on the other hand, are my bane. Can never get a full tube of shooting without having to fiddle with the damn bolt...
My problem with the 525s is the 'hollow point'. It's not a damn HP, it's a half-millimetre dimple that doesn't do diddly for expansion.
