are you supposed to still hold the forearm of the gun when you're shooting off a prop? (in my case it's a couple of rolled up jackets) or do you just let it sit on there? I've been holding the rifle in my hand and laying my hand on the brace and trying not to grip too tightly on the stock but sometimes it feels like it's going to leap right out of my hand and that makes me a little nervous.

i've only been going to ranges since the weekend before christmas, as far as i can remember through my years every other time i have shot it was either actually holding the gun in my hands or propped on a tree. i'm kind of new to his hehe.
