How I decided which one was an accident...literally. I was checking a magazine, for feeding, in my shop(steel side/roof 2 story, 2x6 construction(insulated)), in the second floor gunsmith area. I was stupidly using live ammo, and the rifle slam fired. When the smoke cleared, I assessed the damage...I always point firearms in a safe direction, and in this case it was towards a wooded hillside, outside my shop. So the bullet went through a Doskill, two rifle plastic case, stored in a gambrel roof pocket, and hit a roof rafer, and stopped. The VMax bullet expanded when it went through the case, and when it hit the roof rafter, spent it's energy before punching a hole in my pretty steel gambrel roof. That was enough evidence to get the 6.8 SPC 110 gr. VMax load selected as my home defense round. It is going to stop before going through a number of walls, if it hits anything besides wall board. One could probably get the same results with a 55 gr. ballistic tip, in a 223/5.56 rifle, but I like the idea of twice the weight in the bullet meant for bad guys. YMMV
