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.
Had to go at the sportin goods store. There was pee all over seat. Cleaned it with wad of TP. Applied TP for protection from nasty seat. Turned to sit down. The sensor flushed and the powerful vaccume force inhaled my TP. Not fun.
