The ultra will match any top price gun pellet for pellet specially if its regged, but if money is not a problem then HW100 kt or ks ,far better build quality, 14 shoot mag, best cocking out of all PCPs , comes with two mags , comes with silencer the best one on the market and that's why I have two of them one in .22and the other .177
Doesn't matter what cal as long as you know your set up ,gun ,pellet ,scope and what you are capable of
