More than once, in real life, young men have asked me what kind of rifle they should get for hunting deer and hogs (some of them even aspire to bear or elk but we have precious few of either of those around here. We do have enough deer and hogs to keep a hunter busy though). Oh, and they're on a budget..... (translated= they have no money but plan to have some before hunting season).
99 times out of 100 I will have the same answer. A Marlin 336 in 30-30 with a moderate to low priced scope. I have seen a $25 Simmons 3x9 suffer great use and abuse and still hold true (I've seen them crap out too, but not as many as make it). A 30-30 with 150 or 170 gr bullets will kill any deer on the planet and has proven itself satisfactory for bear and other large North American animals. Any ranch pickup in Texas has a couple of 30-30 round rolling around under the seat, and any country store at a turn in the road has a box of 30-30 ammo for sale. A Marlin 336 (in any of its configurations) is a reliable, sound, hunting rifle, is easy to carry and will function dirty (which is how way too many rifles have to function).
In my opinion, the 30-06 is the epitome of firearm development. The 30-30 helped put it there.
