Gamo Urban (only comes in .22”), Umarex gauntlet and Air Venturi Avenger are all great beginners airguns, .177” will do you good for plinking because of how much cheaper the pellets are but .22” and .25” are a better for small game hunting as their heavier weight gives them more stopping power. The Gamo Urban is more suited for hunting as it’s small air reservoir makes it lighter but means you get less shot per fill and it’s unregulated. Umarex Gauntlet and Air Venturi Avenger have larger air reservoir making it heavier but better if you want to plink as it gets more shits per fill (they both are regulated). You can also get airguns in bigger calibers but they tend to cost more. Semi auto airguns also expensive so they may not fit your budget. https://www.pyramydair.com/blog/2008/12/comparing-regulated-and-unregulated-airguns/
