You only have to register your car if you plan to drive in on public roads. Most gun registration proposals would require registration whether or not you were using the gun on public lands. You already have to have a hunting permit to hunt on public lands (or to take publicly owned wildlife on private land) in most states. The purpose behind gun registration is very different. If you don't think gun registries would be abused in the US- look at the State of Missouri recently leaking its CCW database to the IRS and even worse- look at what happened in New Orleans after hurricane Katrina in Louisianna, where guns were stolen by armed members of the military from law-abiding citizens.
