So how many times has a bystander been injured in reality? What’s the risk assessment look like? How high is the probability of bystander injury. Then how does that all compare with commercial ammunition?
If you were a Diggle member, you could speak to several old-hands who were witnesses to a fatal accident involving a handload. This was back in pistol shooting days when the cylinder of a 44 Magnum revolver failed and the shooter standing next in the line was killed by a piece of metal blown into his neck.
Norman Clark the Rugby gunsmith and who was (for all I know still is) a member of the NRA's technical/safety committee told me maybe 20 years ago that factory ammunition 'issues' were more common than those involving handloads. However, 20 years ago the ratio of factory to handloaded ammo fired at Bisley and on MoD ranges was far higher than now applies, and amongst the latter there was far less emphasis on 100% performance maximisation. Given some of the things I'm told and occasional pointers like a 6.5X47L case I picked up on a firing point a year or two back, that might be read now as 110% performance. Whether there are large numbers of incidents or not, the fact is that there are some involving handloads, and that even if it is from a very small base, the trend is one of a steady year by year increase, not stable state or reduction.
Whether you agree or not, the NRA is bound by three sets of obligations: a moral one to those who use its ranges; one to the MoD which sets out the range safety rules for the NSC Bisley ranges among others; finally, a legal obligation under national safety legislation to ensure dangerous practices are identified and remedial action is taken.
think incompetence is a bit harsh, carelessly or distracted yes, surly nobody would intentionally due to lack of skill aim to produce dangers ammunition.
As far as I'm concerned, producing dangerous ammunition is nearly always negligence. Lack of knowledge and/or incompetence, even without intent to cause harm, isn't acceptable as a reason / excuse, and whilst a momentary distraction or 'brainwave' is maybe human, it still doesn't excuse negligence.
Think motoring law. There is a guy who did several years prison time, maybe is still doing it, for causing an accident that resulted in other people's deaths because he was distracted for seconds by recovering a sweet and unwrapping it while driving. He accepted full responsibility for his actions whilst you'd say 'But for the grace of God, that could happen to any of us!' You can argue this issue either way and I don't see it as clear-cut either, but legally it's very much so.
