I just purchased a marlin 336 30-30 yesterday and was trying to find a good round to use for deer, I'm not in a huge hurry for it cause I was given 2 boxes of ammo which I will probably use some to sight it in. Thank you in advance.

Why not just use the standard recommended 170 grain flat point? Lighter bullets are available & can be used but I'd stick to the 170 gn which, IMO, is a good balanced choice between effective killing power and range.

Winthrop,
I have to agree with Goldtrigger.
Mel Tappan (R.I.P) -who wrote "Survival Guns" - recommended in his book, for the .30-30, "Only buy the 170gr. loads."
He suggested short range sighting-in point is 23 yds. +1.5" (high) @100 yds, 150 yds is suggested optimal range for zero, and -4.5" (low) @ 200 yds.
Hope ths helps, Good Luck with your Marlin 336 .30-30.
