Hi, I have a .30 cal Rosso and I’ve shot it out to 110 yards using the 44.75 grain JSB. It shoots them at 870-875 FPS. It’s an excellent gun and the trigger is amazing. I’m sure I could get it out to 150+ yards but I wouldn’t be shooting anything larger than a ground squirrel/ prairie dog at that range. It would have roughly 30 fpe which can put small game down provided you hit them in the proper spot. But seeing how there was only 3 Rosso made in .30 cal (at least from my understanding) it’s really not a gun you go hunting with unless it’s off your back porch, lol.
Anyways if I remember correctly i was getting 1.25” ctc groups pretty easily and I’m sure I could improve on that if I really took my time and practice with it. Hope that helps you a bit.
