Just received these data from Luke at Hodgdon. Very, very helpful, and 5744 is suddenly in stock in many places.

Thanks for posting that. I emailed Hodgdon the same day I revived the 450/400 thread, and Luke replied yesterday saying that there is no pressure tested data, just software generated data originally from AA ballisticians. He didn't include any data in the email.

Thanks for posting, I'll have to print out this and compare to the numbers I generated using the Accurate formula.

Always like to cross check.

Keeps me from blowing things up. I hope.

That would be a fun one !! We have a 405 Win.. But your brass has a much more spacious cavity.
