If I were to keep just one, I'd ditch the .270. Although there's nothing wrong with a .270, the very simple fact that your wife gave you the .30-06 to honor an important day with something she knew you'd like is a treasure unto itself. No such importance or significance is assigned to that .270.

But from a practical perspective, while the .270 is slightly flatter shooting, it's not so much flatter shooting that the .30-06 will be a liability. If you can't hit it with a .30-06, you're not going to hit it with the .270 either. You're limited in what the .270 will throw, while a .30-06 can chew through everything from 110 gr varmint bullets to 220 grain bone-crushers and everything in-between.

Were it me, I'd swap the .270 out for something in a different cartridge and game class. A .223 or a .243 would be first on my list. If you go bigger, you'd really have to start at the .338 WM to gain appreciably over the .30-06.

The .30-06 is a superb, all-around chambering. Your wife chose well.
