I would definitely use the Gold Dot over the XTP for elk. But i find no reason not to use the XTP on deer. I've found they perform great on deer size game. One of the biggest buck I ever shot (a legitimate 200+ lb fell to a "petite" 200 gr 10mm XTP after only a short run of about 45 yards. Complete pass through destroying the lungs. But I'll be the first to admit the Gold Dot is a tougher bullet.
