Tcrocker: Apologize for completely stomping on your thread, but it just sort of happened.
Shadow: Thanks, she is a beaut...bout the only reason it hasn't ended up in the trash, lol!
Float Pilot:
I know what exaclty is happening. When I pull the bolt to the rear, when the rifle is shouldered, the bolt rotates so that it sits over the ejector as the ejector tries to "pop-up". So, both slots, the receiver slot and the bolt slot, get misaligned. Its only a hair over the slot, but enough to keep the ejector from coming all the way up. It looks like the ejector has a slight bend at the top, towards the direction that puts it under the bolt.
The picture I show of the double feed shows what happens after the bolt has been furthest to the rear and pushed back to chamber the next round. By staying on the bolt face, it picks up the round in the magazine and causes a double feed. THIS HAPPENS WITH EMPTY AND LOADED BRASS.
Now, I mounted a scope on the rifle since, and since I action the bolt like the blade method I showed above, I rarely get the problem. However, if I keep full control of the bolt, without just flicking it back, it will cause that failure to eject problem. If I let the bolt handle ride against my extended index and middle finder together and flick it back, it ejects every time.
CZ already gave me an authorization number to return the rifle, but I'm holding onto it until I get my load development perfected and I put about 6 coats of tung oil inside and outside the stock...man she is pretty!
Load Development:
Bullet: 286gr Prvi
Brass: Prvi
Powder: Varget and AA2520
Primer: WLR
Velocity: 2390-2400
Notes: Varget and AA2520, both at 58gr, gave just under 2400fps and grouped better than the 50yd factory target by CZ. Hornady 286gr bullets identical velocities and Standard Deviations as Prvi 286gr bullet!
Scope: 1.75-5X Burris Signature Safari, post reticle, mounted in CZ mounts supplied with rifle.
Below, in the orange sticker is a 4 shot group! I was so happy about the 3 going same hole, that I jacked up that last shot that went left a bit, doh! (Shots outside orange were sighters to dial in the scope)
