There used to be years ago, though I have the impression that unfortunately the publication/organization didn't survive the online advances of information dissemination. I've scoured articles online at times to enjoy a good Traditional Muzzle loading hunting yarn to fill the void. The NMLRA is a wonderful organization, but, as you noted what you are looking for, their publication, though enjoyable, isn't chocked full of plenty of good fire and smoke hunting adventures page after page.
There are some good, old books on the subject, especially African Hunting stories from the 1800's to read. Hope you find what you are looking for. Share with us, too, please.
