An IPSC shoot I was at was over & a couple of guys were practicing. A couple of old thick stop plates had been left out previously & had been cratered by some fools with rifles. Someone fired a 45 at one... the bullet struck a by-stander. There was injury & the Police got involved. It was determined that the 45 slug had been turned inside out by the crater.
All damaged plates were destroyed & nothing was left out again.

Flat steel plates were deemed to be safe for lead pistol bullets which splattered...
It was thought that the craters were caused my HV jacketed 223.

Hope your wife is OK.
