That's what they're saying. If you have the old powder and it hasn't deteriorated you can use the old data. I'd use current data with any new powder.
I don't think he was trying to make a magnum out of your .270 and neither should you. Find the sweet spot for accuracy and you will have a very effective game getter. Those last fps only make a difference when looking at a chronograph display. The targets really don't care.
