The configuration of your FX Panthera Compact Hunter .30 Cal is, in my opinion, the perfect one for a .30 Cal air rifle:
Short, accurate, powerful and a lot of shots per fill.
I am tempted to buy one with that exact configuration.
Great minds think alike, I guess!
For this purpose before, I had a perfectly tuned .30 Maverick that was pushing 100fpe, but I've since given that to my cousin so I could test out the .30 Pcat HC. I kinda took a gamble letting that Maverick go in favor of this untested idea with the Pcat .30 HC. However I think this little rifle really is the perfect configuration for coyote hunting.
I get at least (2) 13rd mags out of it even with it set at 175 bar. Right now I am using the 8rd Orion mags to clear the cantilever mount on the ATN scope, as mentioned above. About the tune, I have a video on my channel that shows how I set it up. It required the Huma 14.5g hammer weight. My tune is really consistent and the gun even stays the same velocity in super cold weather - which is pretty damn impressive. I think the short impulse valve and larger transfer port help it be a good cold weather airgun. The Maverick was OK but in extreme cold the velocity was a bit squirrely. So far I am not really seeing that with the Panthera.
If you end up snagging one, talk to Tom at High Pressure Pneumatics. That is where I got mine and he leak tests all his guns for several days before they go out which is nice. Link in my signature. Tell him I sent ya!
