My son has taken the hunter/safety course, passed with flying colors, and my brother gave him a shotgun for his birthday. My husband hunts deer with a bow, but my son wants to use a gun. The shotgun is the only gun bigger than a .22 that we own. It is a Mossberg 500 12g. It has 3 choke tubes (modified, improved, and full). We are planning on perhaps buying an cylinder bore choke tube for it as well if necessary. Anyhow, problem is probably obvious - not really the right gun for the target (whitetail/mule deer in WA state). Is there any way we can make this work without spending a lot of money on this gun? With perhaps the right ammunition? I would really like to get him a rifle, but it's not in the budget right now.
