I purchased this .25 taipan standar with the intention of change the barrel to a 15mm TJ 1-22 twist. Why .? Because they suck . I have never found a review of the .25 that at least was some what close to the accuracy of the .22 . I personally have had 2 including one of the first original long and it simply can't shoot the 34g pellets in a aceptable way and the 25gr where at least aceptable.. it was really rare for me because I have shot cheap guns like the hatsan or krall and they have shot way better.. THIS least batch of taipan have won the barrel lottery it shoots Great almost any pellets you throw at it including the 34gr wich make the gun as silent as my .22 .. and I was testing at 94y + with pellets .. I'm more than happy with this purchase this kind of acurracy was what i being looking for in a .25 for the last 6 years.. OF this las batch there is only one left .. at only $1,100 what a bargain.
