I am looking for a recommendation to be used for hunting, I like the DIAMOND D CUSTOM LEATHER Guides Choice Leather Chest Holster but they do not make a scoped version.
I'd look at the Bianchi HuSH shoulder rig. It can also be used as a belt holster and it can fit large scoped type hunting revolvers.
It was engineered by noted outdoor writer & handgun hunting expert: Dick Metcalf.
