Brenneke slugs in a Parker or other vintage guns ?

[Blue Collar]

Has anyone considered "cut shells"? In times past when money was tight and food was not obtained from the grocery store, "cut shells" were a solution to the dilemma of not having slugs or a gun that would shoot them.

Before the controversy begins, my question is, "has anyone considered?"

My grand father brought home a number of deer, and he only owned a model 12 and #7 1/2 shot shells. I don't know this to be safe for any firearm, just a consideration.
