Thanks for looking at this! I’m assuming this is a QuickLOAD output? If I’m reading it right, the max CFE223 charge would be 65.7 gr for the given parameters?
Tannhauser,
Yes, the output is from Quickload. The table of various powders I provided is about 3% below SAAMI max to allow for variations in powder lots etc. Keep in mind, since a lot of Whelens were built on odd actions, the SAAMI specss are pretty low, at around 58K PSI. If your rifle's built on a strong modern action, you may have some additional room to play. As always, if you choose to play, do so carefully.
