The last time I had my SRH .454 to the range the cylinder locked up and I figured that a reload primer must have backed out when I fired a factory round, The cylinder opened up after awhile so I didn't think I would have any trouble when I took it out today. WRONG. The first round fired did not feel or sound right. There wasn't any recoil and the sound was more like an 32 S&W. I unloaded the cylinder and checked the barrel and right below the crown was the bullet lodged in the barrel. The range officer had a rod & hammer so we got it out. After that the cylinder would not shut and the cylinder latch was stuck. I bought the gun new in 2001 so I'll give Ruger a call tomorrow to see if they will fix it w/o any charge.
