Another warning .17 hmr ballistic tipped CCI

[User00039]

Found 98 out of a 200 box split - get on well with my RFD so even though they are 5 years old, they are being exchanged for a new box from the supplier.

Will be checking the new box…

Got a call from a mate yesterday…. he’d just had a nasty experience with his CZ452 .17HMR and Hornady rounds…. he turned up with the rifle this morning and we think we’ve worked out what happened…

Chambered Round1 (probably had a split neck), pulled the trigger, didn’t notice anything untoward with the shot(or lack of it) being focused on the rabbit;
Chambered Round2, bolt a bit heavy going forward….
Ejected that and chambered Round3, no resistance on the bolt… took aim, pulled the trigger, big bang, WTF?! Left ear ringing.
Opened the bolt with the case stuck to the bolt face and fractured around its rim…

Inspecting the remaining rounds in the box… these are/look like an older batch of Hornady with dirty brown/red tips compared with a new box with bright red tips. 4 out of 24 have split necks.

We reckon the sequence of events was …..
a) Round1 had a split neck, with just enough effort from the primer to push the bullet out of the case into the lands;
b) Chambering Round2 pushed the first bullet further into the lands whilst pushing its own bullet back into the case;
c) Round3 went in behind the lodged bullet and on firing, the bullets got 10cm up the bore before the rim of the case gave up the ghost.

The magazine stayed in place and the next round in the top of that is dented on the shoulder. There are powder kernels in the action from Rounds 1 & 2

So, a lucky escape but 2 bullets lodged up the barrel… he’s gutted, it’s a tack-driver and reckons he’s only put around 200 rounds up it. (Rabbits have only really made a comeback on this bit of ground this year)

Photos…
Bolt face, he broke the body of the case off.
4 marked rounds with splits, Round2 with the bullet back in the case, the next one in the magazine, the case body of Round3, balance of the box.

Next question… how to get those stuck bullets out on the chance that it didn’t bulge the barrel and is still a tack-driver…and carry on as before whilst inspecting rounds for split necks…..or let the gunshop pursue the ammo importers for a new rifle with all the inconvenience and delay a variation entails?

cheers

Glad no one hurt. Good luck going after GMK, they seem to have no interest what so ever. I'd start with RFD.

I have run into that more times than not in the firearms industry. Rigid business models seem to abound.....
Or the opposite like CZ who ditched the 527 when they finally got everything right. ~Muir

Ah, now that's when a marketing dept start to win the battle over the engineering dept lol

Maybe a naive thought to the point of being silly but would obturation not seal the case split?

Not when it happened to me! Blew back out of the gas relief port and jammed the bullet into the rifling. It was the last straw for me, and I sold the hmr.
