It really is too bad that a pressure test was not conducted on your remaining loads, that would pretty much settle the issue IMO.
How does testing the remaining rounds prove that a mistake wasn't made with the round that made the gun blow up?
Most people who've been reloading for any length of time have made mistakes.
Well I said pretty much settle the issue because there is always a chance of a mistake but within a single lot of handloads probability is that the lot will be consistent. We are not talking pistol cartridges where he could have double charged one of them. Anyways nothing would be conclusive but it would be a far cry from where we are now.
