dkees:
I went out to my stash and found a box of Remington I bought several years ago for a .32-20 M&P that I have.
It is Remington brand, 100 gr. soft point, part number R32202. On both end flaps are the following statement:

FOR USE IN ALL REVOLVERS AND RIFLES

Good luck in your quest. I think the stuff is still out there to be had.
