I just traded some 7.62 and cash for ranger 180gr subsonic law HP. I have never sold anything on the web but would like to give back to all the people on here that have given me such good info my questions how much would the shipping cost? and is there special shipping for ammo? what are my options on payment? how do I know the person is who they say they are? is there a rating system on here for buyer's and seller's?
