I would look at a FX Boss or some similar .30 cal offering, that fat .30 pellet will buck the wind better than a .25 and from what I have seen from past competitions the Boss is pretty accurate (at least at 75 yards). If you really want to go for the gusto and have a purpose built long range airgun, then I would say look up the Talondor .257 and be prepared to buy some casting equipment .
You reeled me in with the opening line, not a good way to start a topic. David
Who are Tim and Lloyd? Great responses, all. Thanks again.
