I had another idea that might work to get the NAS3 cases to work in the strait-pull config. AI chamber... After some measuring I figured out that the reason for them jamming the action is that the shoulders are out of spec. This effectively makes them have zero headspace, and then they create pressure against the bolt face after being fired.
From what I've read, full power 223&5.56 rounds shoot well in a 223AI chamber.
So, is anyone here with a strait-pull willing to fire a few factory Phantom Wasabi rounds if I mail them to you? The out of spec that I'm talking about is literally a difference of about 1 thousandth, and a tap on the bolt handle with a rubber mallet, stick, boot etc. Not terrible, but not satisfactory either. So, it won't hurt your rifle, especially if you lightly grease the lugs. Avoid oil and grease on the bolt face though, as that'll just make it even tighter, and give us false readings. Clean bolt face first.
I'm even optimistic that we can get a second loading out of them with neck sizing. Once I verify that they work once, I'll order a neck sizer and get a chamber reamed for AI.
Probably need to tweak the charge after they are fireformed, but I've read of instances where people used the same charge. Either way, I'll be happy with 1 or 2 firings, as the cases are not very expensive for a low volume hunting rifle. Shoot bulk for practice...
