I'm 350 rounds into my 3rd 2000 round challenge with my .38 super Colt. It seems once I realized I didn't need to clean my pistols that often these 2000 round counts just seem... Normal. So I had a pistol/carbine match this weekend and on the last shot of the last string of pistol fire on a stage the gun went poof rather than bang, I felt sharp impacts on my face [eyes protected by Smith Optics ballistic glasses]. There was smoke coming from the action and the slide partially out of battery. The pistol was frozen and had to be pounded open and stripped. Bits of brass fell out as it opened. Once the barrel was removed the blown case head was evident [trying to load picture]. It is a .38 super +P case. The case had to tapped out of the chamber. Not wanting to quit the competition I reassembled the pistol, checked it with different ammo and continued on.
I'll count this as a stoppage due to ammo. The pistol functioned 100% for the rest of the match so the test will continue as well. Some lube was lost during the clearing of the pistol which will not be replaced.
