They are actually made by Nosler. The accubond is a controlled expansion bullet designed to give the ballistic performance of the ballistic tip with the weight retention of the partition, the ballistic silvertip is the ballitstic tip with a lubalox coating and a different color polymer tip. Neither are what your post asks for. Howeverfor deer size game either will give excellent performance as will any standard construction bullet. I suggest you buy several different brands of ammo and bullet weights and see what your gun shoots the best. When I say standard construction I mean corlokt, pp, speer hot cor, etc. Pick a bullet weight and go from there. For the 300 WSM I'd say 165-180 gr. Both will do well on deer.
