In my Panthera Compact .25 Cal I have two bottles, the small 300 cc in the rear and a 580 cc in the front.Different animals! You're comparing a bullpup with a 580mm barrel and a 480cc bottle to a compact rifle with a 400mm barrel and a 300cc bottle.
A better comparison would be the BRK Ghost to the FX Impact, or the BRK Pathfinder to the FX Panthera Compact Hunter
Given this information, the major difference would still be the difference in barrel lengths (580mm vs 400mm). It will take a lot more effort to push the same projectile the same speed out of the shorter barrel.In my Panthera Compact .25 Cal I have two bottles, the small 300 cc in the rear and a 580 cc in the front.
If I would buy the Ghost in .30 Cal it would have a 700 cc bottle and if the Panthera it would have the two bottles, as my .25 does.

Works well. Just the rear bottle do not let my right hand to be in the must comfortable position on the grip.No clearance issues with your 580 bottle & moderator on the compact hunter ?
