Anschutz settled on 27.2in and 26in (69cm and 66cm) in the mid-1960s for their single shot Match 54 target rifles. Other than a 50cm/19.7in on the 2007/2013 in the 1990s, they've stuck with that.I believe most Anschutz barrels are in the 25" +/- a little. They seem to shoot about as good as anything built in 22LR.
Other current Olympic rifle makers are in the same ballpark: 25.6-28in (65-70cm). Some older rifles had 29-30in barrels.
