Split Necks 17HMR
« on: July 28, 2009, 02:55:52 PM »
With a early box of Hornady 17gr V-MAX  I had seven out of 10 rounds split  the neck and some of the case.
This is a new 24" SS barrel for my Encore.  Was this a problem with early Hornady ammo?
I have not had a chance to shoot any other ammo out of the rifle.

Thanks, Eddie

Lots of possibilities, but yes Hornady did have problems with some of the earier lots of ammo - lots of problems in fact.   TC also had problems with its chambers when they first came out (in the Contender barrels anyway - don't know about Enclores).  You'd think both companies would have it all figured out by now though.

FWIW, I bought a life time supply of the earliest Hornady 17 gr V-Max ammo as soon as they had a final configuration on it.   I have 3 HMR's and none of them have ever had a single problem with that ammo.

I split some of the early ammo in my Savage, but not in the HMR pistol barrel for my Contender or the much later rifle barrel (Contender).  I don't have any of the early stuff any more, and don't do Encores so can't help with that.

The stories that I have heard was this;CCI made the frist case forming for most USA 17 HMR & machII brass.  They didn't anneal the brass before forming. This resulted in neck spits. All others (over sea's) RWS & Eley did anneal their brass first which resulted in no neck splits. You know about hear say storys.
