You can't go wrong in choosing between; Wildcat, Matador or Lelya, Cricket, Vulcan or Veteran. I'd shoot .25. The 33.95gr JSBs will require some extra power to shoot them in the 60 FPE range and I'd say the Cricket, Veteran Long & Matador Long is up for that. But to shoot the 25.39gr JSBs in the 45-50 FPE range any of these will do it well out of the box.
I absolutely love the Vulcan for shooting the 25.39 pellets. Compact, agile, deadly accurate and forward cocking. The Wildcat compact & Lelya has these same attributes as well.
The Veteran and Cricket are great pups. I like the Cricket for power tuning (60+ FPE) and shooting off the bench. The Veterans, all versions, are great bullpups. Its the only pup here with anti-double load. It's got an amazing mag system. If it had forward cocking it would blow all others out of the water.
