I don't own a SAUM, but I do hunt and reload for a .300 WSM. I set the bullets as far out as I can while still retaining reliable feeding. I have shot both the ballistic tips and Accu-Bonds into sub MOA groups. I tend to like the accu-bond for hunting, simple because I may get a close-in shot, and I like the added insurance of a bonded bullet. I neck sized once-fired brass from the rifle they were shot in, and I shot 15 shots into one raged hole at 100 yards from a Caldwell Lead Sled. No, you don't need the .300 Mags for deer, but if you can handle them and shoot them well, more cartridge never hurts.
