I haven't done what you are talking about, but I did have a leather bullet belt for a 44 mag. If you get it and its leather I would check on the shells after it sits for a while. My bullets would get oxidized pretty quick for some reason. The shells would get pretty nasty. I had a 45 70 one time and if I were to guess the cases were quite a bit bigger than the 44 and may cause an issue.
Recognize that taking real away from real is ruining respect and genuine values in real life and in real wildlife. If you dont care to, you may have already become too corrupted by man's greed and unethical new ways.
