Have any of you guys heard of problems with HMR ammo ? Here in the UK we have had a worrying number of instances where a bullet has not left the barrel, this has gone un-noticed so the next round has caused an explosion. A friend of mine was shooting with a newbie and this happened, it blew the bolt out and also blew the magazine off firing two rounds in there. Fortunately no-one was injured though I think his ears are still ringing. The dealer has informed the importer of the ammo (he hasn't said which it is) and they are going to replace the rifle but it's only a matter of time before someone loses an eye or is killed. I know most experienced shooters would realise something wasn't right before firing a second shot, I had a similar thing once with a 22LR bullet however mine had left the barrel but I checked the bore anyway. I just wondered whether you had any knowledge about this ?
