I've been shooting for about 45 years and, as far as I can tell, I've had what I believe to be 3 different experiences with out of battery detonation "OOB"s. Considering the many 10s of thousands of rounds I've fired and the large number of guns I've owned, that's probably not out of the ordinary.
I did start a thread a while back to review the issue our of battery detonations. When you look at that thread, as I think you should, you'll see that quite a few other posters shared their experiences; so much so that this is was actually quite an informative thread.
The thread starts-off with me mentioning that I had had an experience where I had been firing reloaded ammo out of a Thureon Defense 10 millimeter carbine. Too bad for Hitzy, but nothing actually blew up. Instead, I found that among my fired brass was the case which had the head area totally swollen for about 6mms the up from the rim then the case diameter went down to normal. I knew enough, at that point, to immediately understand that this had been an out of battery detonation (OOB), where the swollen part of the case had obviously been protruding out of the chamber when the case had been fired.
I mentioned in the thread that I immediately, put this experience together with information that I had read, on CGN, about another guy who had had the same thing happen with his TD 10mm carbine. I was curious enough about this pattern that I tested my TD 10mm and my TD 9mm carbines and found that each could fire out of battery.
The test method is in the post. As an aside, I tested my Colt 9mm carbine and found that it could not fire OOB, These insight prompted me to start the thread.
As people added their experiences, in the thread these reminded me of two other experiences I had had - a lot further back - which became clear to me were also OOB situations. One was with a 22LR pistol - which suffered some damage firing factory 22 Aquilla ammo that Canadian Tire had been told not to sell.
The other was a case where I was firing a converted auto M14 in 243 using sub max reloads of H414 and 100 Gr soft points.
I don’t experiment with reloading as you guys do, but am a boring guy who just loads ammo for my two main shooting sports, hunting and IPSC. I usually load long batches on a Dillon 550B - hundreds of identical rounds at time. Once a run of identical rounds are produced, they go in a bag or box and are labelled.
I have my dies set adjusted and left for years in D550B individual tool heads (one per caliber). That tool head includes a flow through powder die with a powder measure mounted on that. The powder measure never comes of the tool head and don’t uses the same powder measure for pistol powder and rifle powder or whatever. Everything stays in one configuration.
On the day in question, I fired at least 20 rounds without issue, shooting offhand. After that round count (and I don’t know the actual no.) a round from that same well-marked batch grenaded - seriously damaging the gun.
That was many years ago and I didn’t know what OOBs were so I only thought maybe I’d made a reloading error – but I couldn't imagine what.
With that reloading set-up I have described you get a round every pull of the handle - and if you were try to do a double throw everything would be obviously wrong. You’d be trying to put a bullet on a completed round (in station four), you’d be trying to insert a new case in station one – where a case already was, etc. and the powder would over-flow.
One of the posters mentioned that he had lost an eye to his Springfield Armory M1A1 gun due to an OOB - and when he said that, things clicked. I now am convinced that my M14 experience was an OOB.
I’m leaving stuff out so read the whole thread.

My experiences are posts 1, 5, and 14.
As recently as 6:20 this evening Hitzy was posting
“Makes much more sense now how he blew up 3 guns...”
Hitzy did that post this evening even though kodiakjack
had already read the thread and 10 hours early and wrote
“
Not with his hand loads.” ... after someone else made the same false claim.
I don’t think Hitzy would like you to read post #18 of thread because it kind of dumps a load on his persistent efforts to claim that this event must have been as a result of my handloading error.
This is what I’m referring to.

The M14 was repaired and is still in my collection. No damage was suffered by the TD carbine and Canadian Tire acknowledged blame and paid for the repairs to my Erma EP 22 pistol.
The number of guns I have blown up as a result of handloading - or otherwise - is ZERO
