So, finding myself completely out of 17HMR ammo, I called in at the LGS to pick up my usual Hornady VMax 17 grain.
The only 17HMR he had was Remington Premier 17 grain!
Now I would'nt normally buy Remington ammo for my 22LR and have always been happy with the Hornady in the 17.
Being a bit reluctant about Remington ammo in general, I did a bit of research.
The outcome of this was that I discovered that the Remington Premier is produced by CCI, which I understand is the producer of my usual Hornady ammo, so off I went to buy some.
I got 600 rounds and passed 250 onto my shooting pal.
Having just put a sling on the CZ, I thought I'd go to the range today to practice shooting "off the sling."
I shot 50 rounds and had 3 hang fires which I have never experienced before.
I made a point of collecting the brass for inspection, to see if I could find the cause.
I'm used to having the odd split cases, but was surprised to find almost half of the Remington cases had split necks.
I got a new box of the Remington ammo and was examining individual rounds and was shocked to find split necks in the unfired rounds.
I checked all 300 rounds which I had remaining and discovered 32 to have split necks!
I dont know if this could be the cause of the hang fires but, maybe if it is old stock, the splits have allowed moisture to get into the propellant or primer, causing the issue.
Anyway, I just thought it was worth making folks aware of this, as I will be making my LGS aware on Monday morning! LOL.
