Well the time has come!
With the new power plenum out and being supplied on the new guns FX has added the 9mm/.357 to the line up!
So I figure they will make a division in the calibers (.117, .22, .25 , .30)and then add the bigger Plenum and bump into the big bores eg: ( .357/9mm , .40 , .45 , .50) and then if they go that far they may as well go to the real big boys of the black powder standard ( .54 ,.58 ,.62 ,.72)
Now you may need to carry a SCUBA tank on your back to hunt with the top calibers so you can get multiple shots , but to shoot these calibers there are probably though that would do that! LOL
The air gun world has hit the ground running now and it's a clean slat as to how big and how far they will go.
I for one am glad to be alive to see it ,I so enjoy my air gun on our farm ,Pesting is a blast.
