Am trying to make a decision on buying a high-end PCP to be used for pesting – ground squirrels, eurasian doves, pigeons, etc. out to 100+ yards. Kind of up in the air on caliber – .22 cheaper and more available vs more knock-down power with .25. Have my choices narrowed to either a Uragan Standard Synthetic or a RTI Prophet Performance. How is the Uragan to work on? The RTI is said to be pretty straight-forward in that respect. The fact that one can easily change calibers with the Prophet is a plus too. This will probably be my one buy once/cry once PCP purchase so I want to make the right decision.
