I don't hunt, but the PCP rifle is a very capable machine, feel free to compare to 22 LR. I know some people in USA competing with airguns in a 22LR tournaments and winning !!!
I have two PCP air rifles, both setups for target shooting, and I am a large volume shooter, roughly averaging 8-9 K shots per year. I was training hard for competition but recent years were just messy for long travels so ended up just having my own fun game.
The FX Impact MK2 in .25 with several 700 mm barrel liners, each have different twist rate, let say 1:32 or 1:27 or 1:24 or 1:18 or 1:15.5 (one twist : over those length in inches). Each liner is a different personality - for different projectiles. This my airgun is tuned currently for 100 meter rings, and it is capable of MOA precision with pellets, I can change the power tune right on the gun and shall be able to shoot slugs to 200 and 300 meter rings. This airgun base price starts about $3300 and very quickly can double the cost if you not careful with your wallet.
The Edgun Leshiy2 is a .22 semi auto, I have same several different barrels (different lengths and twist rates) and also I made an adapter that will fit the FX liners as well. I tuned this gun for speed siluettes up to 100 meters, and I was shooting it in my gunclub at the 22LR range. I have friends in US who shoot this same airgun up to 200 meters but I have not tried it yet. The US folks using it mostly in hunting scenarios. This airgun base price starts about $3500 and the sky is a limit.
Also, I have a compressor that can reach 300 bars, and four scba (firefighters breathable air) tanks, with my style of shooting I need to refill at least ones a month. Each tank can give me roughly about 700 shots, but actually I never count/document it just guessing.
And then comes the optics, me personally like high power glass to zoom in a 100 or 200 meters target I like to watch how my projectiles chewing the paper edge.
So, pretty much the PCP airgunning is like an iceberg, you see the rifle or handgun, but the total cost is ... a rabbit hole is piece of cake to compare.
If you need to take care of your wallet but want to save on primer you can still get brake barrels high quality starting from $700 ish. If you targeting sub $500 better stay with 22 rimfire.
