What is Semi-Automatic?
A semi-automatic rifle fires one bullet each time you pull the trigger and automatically reloads the next round. It's different from automatic rifles, which keep firing as long as you hold the trigger down. Traditional hunting rifles, on the other hand, usually require you to manually chamber each round.

Semi-auto rifles are great for various activities. For hunting, rifles like the Ruger 10/22 are perfect because they're reliable and easy to use. These .22 semi auto rifles offer enough power for small game hunting while providing a lightweight, relatively quiet, and manageable firearm for all skill levels.
If you’re into tactical shooting, CQB, or need a rifle for home defense, AKs in 5.45x39 and ARs in calibers like 5.56/.223, .300 BLK, or 9mm (the latter are also called pistol caliber carbines), or any other modern sporting rifle are fantastic options. These rifles combine maneuverability with stopping power, making them the best picks for short-range engagements and home security.
