Yes, I have, but couldn't get a Savage B-Mag rifle to shoot accurately enough for rodents, though it was OK for larger varmints.
While fooling with it, however, I tried some of the CCI .17 HMR ammo for the Savage A17 autoloader, and it not only was superbly accurate in my CZ 452 but got 2850-2900 fps, far more than advertised. (Some other people have found the same thing in bolt actions.) The .17 WSM ammo got around 2950 in the B-Mag, not enough difference to fool with, and the A17 ammo is usually as cheap or cheaper than .17 WSM. Found out it works great on prairie dogs....
