So I went and bought the bottom metal for my savage 10FP from CDI and while I was at it got 1 10rd AI mag. I got it all together and was running some dud .308 through it and at least 2 rounds don't extract all the way I.E. rack the bolt back and it pulls the round all the way to the rear and dumps it on the mag. I happens with both dud and snap caps. Any idea's? And no am not baby-ing it, am racking it just like I did before.
