I was introduced to this style of shot bag,... or hunting pouch when first getting involved with smoothbore flintlocks. It is every bit as useful for a modern shotgunner as a 1700's fowler...
Way to much work into this one. Cut patterns that make it a tapered gusseted bag with welts. That is some hard hand stitching. Bag is reversed while being sewn up then soaked in a tub of warm water in order to punch it right side out. Stained then wax finished. Sinew was used for all the stitching. It has three pockets sewn in and a 3" belt loop.
