Back in the day when I used to shoot a 30-30,I had it dead zero @ 100yds.These days if I was going to hunt with one,I think I'd go for about 1 1/2" - 2" high @ 100yds and that would put me good to 150yds or so,which is about as far as one should be shoot deer with it.It is a good cartridge,but as all cartridges,it has it limitations.As long as you don't try to make a long range cartridge out of it,you will do fine with it.

As Bob Hagel would say"You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong."Good words of wisdom...............
