Read 2 articles recently which I found interesting.

One said the 25-06 really needs a 24" barrel over a 22" to shine.
Noticed browning xbolts are 22" barrels on the 270 & 30-06, but 24" on the 25-06.

The other compared a 257wby in 24" and 26" and amongst factory loads velocities were nearly identical, or less than 30 fps slower in the 24", I think the 2 rifles were the weatherby MKV vs. the vanguard though, so not exactly apples to apples for barrels.
