I own both of what you are probably considering as your options right now: 10/22 and Savage MKII FV (that's the heavy barrel, btw any V in a Savage model means the same thing, heavy barrel).
There's nothing like ripping a can to shreds with a semi, but I will share my evolution of .22 ownership, and I think it will help you some.
I bought a 10/22 because I wanted a semi, knew it had 30 round mags available for it, and if I needed/wanted to change anything on it, it was very simple as everything is modular. The trigger was the first thing to go. It was so stiff, my finger actually hurt from the strain to pull it. It must be 8 lbs, no lie. I replaced it with a VQ trigger group. oops, $200. I then replaced the stock because I was scared of dinging up the nice wood that came with the DSP model I bought. oops, ~$50.00 wasted because I could've bought a synthetic model as I would've changed out the stock just the same on it. $100 for the stock.. suddenly that 10/22 isn't the bargain I thought it was

.
After playing around with the 10/22 for a bit (and I admit, it is fun burning through ammo just because you can) I started to doubt it's accuracy (it still has the factory barrel mind you). I then found a deal on the Savage MKII FV. Well holy crap, compared to that gun, the 10/22 is a shotgun! It is a far better gun to learn how to shoot on because when you miss, you KNOW it's your fault, whereas with the 10/22, it's within the standard deviation.
And yes, you will burn more ammo with a semi than with a bolt unless you consciously try not to, and even then, it's hard. I had a cheap box of .22s I wanted to get rid of because neither gun shot them particularly well. I could easily go through a brick or 2 with the 10/22 in one range session. With the bolt, it was torture going through 50 unwanted rounds lol.
The semi is damn tempting as a first gun, I know, because I've been there. But if you are looking for accuracy, a gun that will teach you how to shoot, a gun you might hunt or shoot gophers with, and you don't want to spend a whole lot, the Savage does come out waaay ahead of the 10/22 when comparing them straight out of the box.
You WILL lighten or replace the trigger on the 10/22. The Savage comes with an excellent one out of the box.
