Do yourself a favor , check out ,and compare the price of ammo for the cartridges, your are considering, then go to walmart and see if they stock that ammo. Ammo is to a gun what gas is to a truck. Even if your rich, ammo availability is important too. Do you want to travel all over to find obsolete or uncommon ammo at 30$ a box ,or do you want to go anywhere that sells ammo and pick up a box for 15$?
IMO a 30-30 or 243 is more than enough out 150 yds, for what you want to hunt. In fact I think a 170 gr 30 30 will penetrate the shoulders of the average hog and deer standing side by side. I dont think people quite understand how powerful even the most moderate "deer" cartridges really are.

Then again, if all that doesnt matter to you, then by all means, get a 300mag or 45-70 and pound away
