17 gn 17 cal projectiles ?

Yeh with the cases splitting. I just sent back nearly 250 x 17grn Winchester 17HMR rounds as they all looked dodgy .
I had out of the first box 25 Split most got stuck after shooting them ( no live ones got stuck) even had one split the case on both sides all the way down I got a feeling it is old stock .
Its not the rifle either as I shot some of that ammo out of another 17HMR and the same thing happened.
