Yea, you're right plane. In fact, I'm now seriously considering purchasing a semi-automatic rifle with scope. Any suggestions as to what type of ammo I should focus on? .223?, .308?, .338? What are your thoughts about the Lapua round?
My personal preference would be 308 or 30-06.
But I don't presently have one of those, My fathers 8mm was excellent .
But I can't tell which would give you the best satisfaction, the thing to consider is what your circumstance and target will be and what you are comfortable with.
Firstly what is your target? You don't want small bore for bear nor large bore for rabbit.
Are you riding most of the way to your target? or does your gun need to be light because the targets are at the end of a hike?
Try not to buy one that you can't test fire, the thing has to fit you too, a gun with unmanageable recoil isn't good, and one with less stopping power than needed can be cruel .
If you are intending home defense , you might give consideration to small shotguns because the range is short and the types of ammunition available allow you to tailor the response to the situation you think is most likely. For home defense the ability or not to penetrate walls becomes very important..223, .308, 30-06 all have the ability to penetrate an attacker , the walls behind him and the door across the street, this does not rule them out entirely , it depends on your circumstance.
Have you seen "Failure to fire"?

The Lapua round?
I don't know, what is it?
