147 what??
9mm or .40 caliber??
Most kabooms I have ever heard of occurred in a .40 caliber gun.
Please feel free to correct me if this is not the case.
Sorry, the original post was about a .40. The Federal 147 referred to is a 9mm round. I am not aware of any 147 gr. .40 loadings that have ever been used by the FBI. My mistake in not specifying.
I am aware of guns blowing up in both 9 and .40. I wouldn't feel comfortable saying "Most" for either caliber. This is simply an admission of "I don't know".
