Is 17HMR enough better than .22LR to justify my getting another barrel for my CZ? I know it's flatter and faster, but does that translate into superior results for birding?
My .22LR barrel is lights-out with its favorite load.
I go to local farms and use my air rifles to shoot starlings and pigeons, etc.
Here is a short video of a few shots taken with my FX 400 Royale .22 using 18 gr JSB pellets at 915 fps.
Video was taken with Samsung S9 mounted to gun with a Sideshot adaptor. https://youtu.be/OLK1kzjhB98
