That's part of what sold me on Ruger, my first .357 Magnum, a Security Six. Had to shoot the hottest loads at the time (Remington High Velocity 125gr SJHP), discovered the forcing cone on the barrel was cracked. Sent it back to Ruger, after it had been replaced several years prior by the GP100. They replaced the barrel, redid the timing, replaced the springs and sent me the aftermarkets back in a baggie, cleaned the pistol, reblued the whole thing.
Didn't charge me a penny.
