Ive used 160gr nosler partitions in mine for years now. Ive never had to track one yet, and seeing that a 30/30 has a lot less power and has killed more whitetail then any other caliber out there, its more then enough gun. Only reason I got one was for the farmers field in wisconsin. In the woods, my 30/30 was plenty of gun. Now for them tough oklahoma deer with armor plating, I finally bellied up and bought a 300 RUM and shoot 180gr partitions out of it,lol. Its more of an out west gun, and a little overkill, but dang it shoots good, so cant part with it. Practice at the range, as you should with any gun of any caliber, and there wont be a problem of bullet proof deer next season.
