Sounds like it’s the same as it always was, having check every round for split necks before you go out. Not for me, I’d say that was not fit for purpose.
I’ll stick with the WMR and .223…….

No mate. There is no longer a need to check any more. I did an item on it a few months ago. The new powder lights up easier than the old.
My last testing didn't reveal any difference in zero either between split and I split. All shot with the same impetus and no squibs.
They had to many claims made against them! Had to pull their finger out!!
Fair enough, I’ll still stick with the WMR in semi auto and .223 for longer shots as I’m loading that cheaper than I can buy 17 HMR.
First shot on game with my HMR resulted in a bullet lodged in the barrel, that and several hang fires over the following months convinced me it was a pile of crap. Shame, as when it works it’s a cracking little calibre.
Totally mate - during covid mine shot so many squirrels - i loved it like a laser - but i was very very lucky in the end - so sadly never again
As in rifle’s are unavailable?
Specsavers?
Be careful - you only need one to ruin an otherwise pleasant day !
I agree, I have shot lots of com bloc surplus ammo and one fine day a CZ 52 with polish ammunition blew the case and that continued down the magazine and finally out of the pistol. No harm to me or the gun. I have also had Korean surplus blow cases in .30M2 Ball one of those wrecked the extractor on the US1917 rifle the other cracked the stock on my M-1 Garand no damage to myself, had I not worn safety glasses I would probably lost my right eye.
No, prescription safety bi focal glasses. Some of my 17hmr ammo dates to 2009 should any of it split I will be quite annoyed.
Some years ago, I spoke to a rep from Hornady who said part of the trouble with the 17HMR cases splitting in this country was the fact that they had travelled long distances, and the vibration caused problems. This always sounded a bit odd to me, but could NP435 let us know if there have been many split case problems in the USA?
Over here you would very much be the exception to the rule!

Nonsense.
The thin brass gets work hardened by the rapid machinery, there is no possible way to anneal the case mouth due to the primer.
The old powder relied on the crimped bullet for good ignition. If and it did, the thin work hardened brass cracked the crimp no longer worked resulting in iffy ignition and totally randomly.
The new powder seems to circumnavigate the problem of work hardened brass.
I really don't know nationwide none of my friends have had the problem and having avoided most of the USA based shooting forums I could very well be uninformed.
The nonsense about shipping distance and vibration is disturbing coming from a manufacturer. My stuff gets plenty of vibration riding about in my CJ7. The only other ammo I got hundreds of split necks in was Turkish 7.92x57 dated from the early 30s, no damage to my body or the Mauser.
