Silent Earth
A True Doomsday Prepper
Sometime the nocking points just push back in, Oh yes one brand of bolt the point actually unscrews so you can fill it with sand from the other end, but if the nock point stays loose just use a tiny dab of silicone sealant, not superglue. A modded bolt up to ten meters WILL penetrate through a winter parka, fleece, vest and a couple of inches of tissue. ESPECIALLY if ou sharpen the bullet point a bit more.
