A sister called her brother and told him that her husband had been put in jail for a felony and that he could never have guns again. The sister kindly offered her brother the felons gun and ammo. A BLR in 7mm mag. Why sure thing said the brother, he would be delighted to have it. Brother picked up the gun and the felons reloaded ammo. Next day, the brother dying to shoot his new rig goes to the range to do so. First shot, KABOOM! The gun blew up with the bolt of the BLR shooting straight back into brothers eye socket. The bolt luckily did not enter the scull, rather it slid around the shooters skull between the skin and skull bone ending up near the left eye. Brother lost an eye and had some other damage but survived. A police investigation determined that the felon used pistol powder to load his 7 mag. I know this to be a factual account because the company I work for paid a dismemberment claim for the lost eye. Moral of the story, be careful of who's ammo you shoot.
