twobit, There was nothing wrong with your Dad's reloads. I started loading later part of 1965 and Lyman manual #45 published 1970 they list start load for the 130gr bullet for the 270 @ 44gr/IMR-4320 and max load of 50.5gr/IMR-4320.

They did change individual granule dia and length for IMR-4320 not listed what year that was done. About 15yr maybe little longer they were going to stop making IMR-4320 it was the powder for the 17 Rem at that time anyway they must of gotten lot of complains as they decide to keep making it.

I think Hodgdon may be the only manual that list IMR-4320 for the 270 with 130gr bullets.

Well good luck
