I'm looking for some kind of shooting rest to take to the range, use on a portable shooting table (although I don't have one yet), or to just sit on the hood of my truck. I've seen some nice metal rests with three legs, as well as some shooting bags. I have no idea what to get or which works best. Any recommendations? I don't want to spend any more than I have to, but am willing to spend enough to get something decent and that will last. Thanks in advance and Merry Christmas!
