I had a tang-safety Ruger Model 77 chambered for the .338 Winchester Magnum rebarreled (Shilen - 24-inch) to .416 Taylor by Atlanta gunsmith James R. "Jim" Shaw (now, sadly, deceased). Although this is still a push-feed action, the conversion was a success, and the .416 Taylor is a very efficient caliber in this bore size. I don't try to hotrod the caliber, but it's easy to reach 2,300 feet per second with 400-grain bullets.
