You will have to go with the Sierra 125gr FNHP for a flat nose bullet to work through tube magazines other wise the 125 Nosler ballistic tip works REALLY well at 30-30 velocity. I know people that just load one in the chamber and leave one in the magazine with tube magazines. It only takes one well placed shot to the shoulder with the ballistic tip on a deer and it is DRT. It is my favorite bullet for deer in everything from my 308 Win rifle, 30X47 HBR rifle and 30-30AI Contender 14" barrel pistol.
