federals tend to be a little more pricey than winny and don't deliver the same accuracy i've found- also the more names they stick on it the more expensive it is- pistols espically seem to choose their brand of ammo for you- some will take anything, others are a good deal more finicky about what kind of ammo they're fed- i've got a beretta that went through almost every kind of ammo there was with the exception of the eley target stuff before it told me it liked winchester wildcats
