OP, if you're really new to the game, don't start with a semi auto rifle.
To many things that knowledgeable people do automatically and seem like common sense, aren't, to a newbie.
Hopefully, you have a mentor and a place to shoot safely??
If you don't have a mentor but a place to shoot, where other shooters are present, get a few suggestions from them. Most shooters are very willing to help out a newbie.
I would suggest a 22 bolt action rifle with a detachable magazine. Even a tubular magazine, under the barrel or feeding through the butt is OK.
Just a lot less things to go wrong during the learning curve.
Not only that, it slows down the rate at which you will use up ammo and will hopefully get you to pay more attention to shooting stances and sight pictures.
Stick with STANDARD VELOCITY ammunition. It's usually more accurate. There will be wails of derision over this but very few rimfire rifles shoot the hot ammunition as well as they shoot standard velocity ammo.
Now, there are a lot of dealers at the top of the page that will have exactly what you're looking for, or you could go onto the EE for a used rifle.
One other thing, many folks firmly believe that new shooters should start off with iron sights. I'm not of that opinion. Not everybody is gifted with 20-20 vision and glasses, especially progressive lenses tend to make sight acquisition difficult.
IMHO, you should take a look at some of the scope/rifle packages that are offered. They're cheaper than buying the components separately.
Once you're familiar with your new rifle, you may decide you're looking for something that will shoot well out to what used to be extreme distances. Many clubs are starting to have matches where they are shooting 22 RF rifles out to 300+ yards, with very specialized and expensive equipment.
