Stock FX Impact Mk3 and Slugs

[Spin]

No, the Seneca does not do it. In addition to being non-regulated, it does only ~50 ft-lb in .22.

I should have specified .22 cal in my OP. My bad.

The reason for .22 is the trajectory slug BC gives in that caliber at high but subsonic velocities.

  People should remember that air rifles  do have an advantage when it comes to physics, ballistics and compressed air over powder burners -  more consistent breach pressures
A well regulated PCP these days offers more stable and consistent pressure propelling the projectile.

Is there a 22 cal air rifle slug with a better BC Tha. 25 cal? I'm not sure I understand how a 22 cal slug will be better.

A projectile of the same weight, but smaller caliber and thus longer, has higher BC, always. That's how ballistics works.

I understand how ballistics work, but are you a good enough shooter to tell the difference between a 0.096 BC vs 0.12? I don't get the point of your thread if you already know the FX guns can do what you want.

Of course nsa is cheaper. They hav 12% discount going right now. And if u take enough u get 15% discount. That’s less than 5cents per round on the 20gr .22 slugs I use

I stand corrected on that. They were much more expensive when they came out.

FX Hybrids are still pricier - .15/round.

Cast your own ammo, .172 comes at 0.003 cents for a bullet. People have installed .172 liners in FXs, easy to match .22lr in ballistics with those.

Honestly, there's no wrong answer; figure out watcha wanna do, then build it or buy it.  You have lots of options, and yeah, it looks like the Panthera is a versatile FX.

I was looking for a "jack of all trades" PCP, and my Leshiy Classic ...  Guess what?  It excels nowhere.
My wife's M-25 and Lelya have more range and both are repeaters 
My Fortitude is easier to fill, has more shot capacity, and is a multi-shot 
The PR900 is lighter and shoulders like it was designed for me personally
The PP700 is more accurate at short range
The PP750 is more compact and uses magazines
The ShinSung Ultra has wayyyyy more knockdown power even if I buy the Leshiy Classic a .35 barrel, plus it's a repeater

But the Leshiy does it all and it does it well enough to where it is far and away my favorite PCP.  I can swap barrels/calibers, adjust the reg and HST, it uses a pic rail for mounting, and it folds up small enough to keep in a small backpack when hiking.  In other words, it does exactly what I wanted it for.  I recommend doing the same: find that PCP that really hits all the right metrics.  If you settle for something else, you're literally ignoring your own desires.
