Yes, and you certainly don't need to be HC/PC to be primitive hunting. In my view that would mean using primitive sights too. I'm sure that's what the mountain man used back in the days.
This is not pointed at you Ron. Just the rules I set on myself when i'm primitive hunting. I like to use a GPR, PRB, BP, and primitive sights. Not perfect, but close. I'd also love to wear buckskins, but putting blaze orange over it spoils the mood.
Of course, i'm no where near primitive now with an inline. My old broken back can't handle a 10lb gun. Maybe in the future i'll get another GPR.
