So far so good along with others in my area using this Winchester Supreme ammo!
BUT . . . has anybody out there had misfires with this ammunition?
I heard some time ago that Winchester make their own .17MMR ammo including the cases or at least have their own manufacturing supplier other than CCI. How true this is I don't know but ever since changing to Winchester I have had no squib rounds and misfires.
This morning I measured the case neck thickness at half way down the neck of a fired Winchester Supreme case. . . it measured 0.011 inch.
It would be interesting to see what other brands measure from a fired case. So Verniers out and lets see if there is any truth in whether Winchester cases are thicker!
I won't hold my breath but if the Winchester appears to be performing we can solve this 17HMR problem with our wallets.
