With the money Kentucky Ballistics apparently has to buy guns and then just blow them up, it would be more useful to get a bunch of different rifles (Winchester, Remington, Savage, Browning, Weatherby, etc.) chambered for the same cartridge, and feed them gradually increasing overloads until they start taking damage - increasing headspace, ruptured case heads, etc.
P.O.Ackley did this decades ago, mostly with military actions. (Surprising many, early Jap Arisakas were among the strongest.) It's time for a repeat with "modern" rifles - the gun rags won't do this because of fear of advertising dollars going away.
