It's in an article in "Pet Loads" called "Loading the Old Ones." Not much detail, since the article covers a whole bunch of older ctgs. but a couple of loads he tested are there. If you'll PM me your email, I could email them to you.

Thanks Mike for the info. Unfortunately I didn't end up with that rifle, so it's looking like I won't be loading 40-72 for awhile if ever.
