I know Winchester 555 is the same as Winchester 333. This is what I shoot exclusively. It works for me and my guns. I have had a little difficulty finding it lately though. I have found this though:

It is Winchester 525 and if you read the box, it sounds the exact same as 555 and 333. Which is this stuff:


Same grain, same velocity, same bullet type, nothing different. So why the difference? What a I missing?

depends on how many times you want to shoot something.  333 times?  525?.....

ummm......................this.
