In my country you can shoot ft up to 28ft/lb and up to 12. Most guys choose .22 for the high power and .177 for wftf division.
I moved from high power with .22 to wftf .177 because:
1. It’s more rewarding hitting a target with a pellet that drops so much and it’s so sensitive to the wind.
2. The gun barely moves and you can make very nice shots, it feels like slow mo, even more with 10.34gr at 710fps.
3. Air consumption is 3-4x better, I shoot until my medium size tank is at 130b, whilst with .22 I needed a refill when I was at 180. I visit the compressor shop much less and that’s a concern removed from the list.
4. Pellets are cheaper
5. You can shoot in other countries as well
6. The most skilled shooters shoot ft in that division
7. Guns are generally less noisy and smaller
As a hunter, most of the times pigeons, I often bring my .177 hw100 in 18 ft/lb vs my rti in .25 shooting 60 ft/lb as it’s much more rewarding and nicer to shoot. It’s just much more comfortable to shoot a tradicional rifle off hand than a bullpup (a powerful .25 it’s a fishing rod, even more with supressor) and when you shoot it barely moves. you can see the impact almost in slo mo, while the .25 it moves so much that’s you don’t know what happened.
It’s kind of like bow hunting vs rifle, a bow might be not as effective in most scenarios but has a different, more rewarding appeal
