had the exact same thing happen to my 1st ruger VT 204. Only difference was, it blew up in my face with a Hornady factory load. Ruger eventually replaced the rifle (took 5 months) with no explanation other than 'overpressure situation'. They did, however, send the gun to Hornady for them to check it out later. Don't be expecting a replacement if they know it was handloads.....
