steve_b_wales Posted June 20, 2012 Report Share Posted June 20, 2012 Yesterday, I went on one of my permissions to re zero my CZ452 17HMR. I was using Hornady ammo, which I have found to be excellent. After zeroing the scope at 100 yards, and getting good groups, I went to load another round, and the bolt would not close fully. I tried it again, and the same applied. I made sure the rifle was unloaded, removed the moderator, and looked down the barrel toward the chamber. There was no light showing through. It turns out that there is a bullet head stuck just inside the barrel near the chamber. The only way I can get this out is to use a cleaning rod, which I did not have. So, I've now ordered one (£23.99) and hopefully, I can tap the bullet head out. I have never had any problems with this make of ammo, and it was lucky for me that the bolt did not close fully, as I would'nt like to think what would have happened if another round had been fired.

redtailhawk1 Posted June 20, 2012 Report Share Posted June 20, 2012 Iv always used the same amo with no issues. But there has been a couple of threads about it now. Thinking of changing now Quote Link to comment Share on other sites More sharing options...

Gimlet Posted June 20, 2012 Report Share Posted June 20, 2012 Why should there be all these problems with HMR ammo? Isn't the HMR just a necked down WMR case? I don't recall WMR being unreliable. Perhaps you just can't neck down a rimfire cartridge. Maybe the .17 Hornet will shake things up after all. Quote Link to comment Share on other sites More sharing options...

Ok, we hear more and more about HMR ammo problems, I have many, probably several hundred split necks over the years, but so far nothing worse. Is the HMR ammo actually getting worse, or is it just that there are so many in use now more problems are showing up? I don't remember any problems in the first few years of the HMR's life, did I just miss it, was ammo production on a lower lever and more care/quality control in place?

steve_b_wales Posted June 20, 2012 Author Report Share Posted June 20, 2012 The many posts regarding HMR ammo have generally been about the necks splitting. My issue was regarding the bullet head getting stuck. I can't recall a different sound when I fired the cartridge, and if it did fire, I believe that the bullet head would have been forced further into the barrel. I'm wondering if I ejected a live round, and the head seperated from the case. Quote Link to comment Share on other sites More sharing options...
al4x Posted June 20, 2012 Report Share Posted June 20, 2012 thats more likely steve I'd clean the rifle well just in case its a build up gripped the head slightly as you've removed the live round. Quote Link to comment Share on other sites More sharing options...
alendil Posted June 20, 2012 Report Share Posted June 20, 2012 That is possible it did once with remington .22LR in my mates new gun he did eject life round and bulet stay in barrel. i use hornady ( only 150 round so far) no problems at all No split cases or anythink but normal fireing.

Perhaps you just can't neck down a rimfire cartridge. Maybe the .17 Hornet will shake things up after all. Yes, it is a necked down WMR. I assume that the necking down process work hardens the brass and causes it to split. I've never had a split or squib round with my WMR. I had just renewed my FAC and got HMR. I had intended to trade my WMR for 22lr. For now I've decided to stick with my WMR and I've changed the HMR for 22lr. Assuming that the .17 Hornet is a necked down 22 Hornet then I wonder if the same problems will start to show. I think I'll skip that one and get .223 next.

steve_b_wales Posted June 22, 2012 Author Report Share Posted June 22, 2012 The cleaning rod that I ordered arrived today, and I inserted it into the barrel from the threaded end. I could feel some resistance, and a quick tap on the rod, pushed the bullet head back out. The head had gone into the barrel approx 12mm, but enough to stop another bullet being chambered (thank God!) I can only assume that I did actually eject a live round, and the head seperated from the case. A good clean of the rifle is now in order. Steve.
