Yesterday lunchtime I had a call from a shooting mate who is also a SDF member. He was out sighting in his CZ American using Hornady ammo and suffered a barrel blockage, result was a badly twisted bolt and a 2" piece of the stock from behind the bolt shattered off, so another ruined .17 HMR. Very luckily he was unhurt.
I am unclear of the exact events but clearly the prev round was a mis fire and the bullet lodged in the barrel far enough up for the next round to be chambered and fired.
I have done a quick search on the net "Faulty .17 HMR ammunition" and it brings up reams of stuff.
I am also aware of the posts on SDF.
Clearly this is an ongoing and serious problem which is not being resolved so I have written to the HSE and asked them to investigate.
Its not really their issue, however if any Gamekeeper or Pest control officer who uses a .17 HMR as a part of their job suffered the above then it could be reported as a Dangerous Occurance and if the shooter was injured it might also be reportable as a RIDDOR if it was a seven day injury.
I await the HSE's response.
