Hi Slowcoach, you are right about trying all the calibres
i shoot them all but .25 is great fun, i have now got x3 , a bsa lightning .25 @11-00fpe
a hatsan stryker 1000s .25 @11.5fpe and a fac rapid .25@48fpe, the stryker is the latest buy and for £120-00 new its a bargain, and shoots well, i had it out lastt night
and shot my 1st bunny with it at 25 yds , the impact noise was dull a thud but no twitching just very dead , its a very underated calibre.
