Yeah I'm not saying don't shoot them. I will shoot any low number after reading the stuff I have now. I don't see any actual difference in the docs that make me anymore fearful of shooting a low number over a high number. In fact I see quite the opposite that the heat treatment can be bad on high numbers as well. I've seen about a dozen reports now of high numbers grenading on bad ammo. One guy lost a thumb. A couple lost an eye and so on.
It's interesting because SA says not to build a magnum out of these receivers. They even state that proof rounds of 70,000 PSI are reaching the limits of what one can handle. One thing I found interesting they say they should not be used for rifle grenades, just like the low numbers. Stating that with the barrel plugged and the 40,000 PSI of the blank ammo, that is reaching the limits of the receiver.
When you read that stuff, that is the same thing they state on low number receivers. So it's just interesting that when you compare them, they speak of both so similar.
But yeah how many of these were built into magnums, when someone wrote in to ask them, SA was very firm on not doing that. That it wasn't safe.

The biggest thing I see over and over on these, check the headspace. They had a substantial amount that would not headspace, so a lot were cannibalized to try to get ones that would headspace.
