In my first thread I had trouble with my new m14 not grouping. I took it back where I got it and had it sent to a gunsmith under warranty. So what I got back is;
they reamed the forcing cone, straightened the yoke and timed it.
They supplied test targets which showed two decent groups with Win 148 match, two good groups and one great group with Federal 148's. A quick mix of my handloads show that it will easily shoot 10 ring at 25 yards, but one chamber that consistently shoots out.
So now I am going to do some serious testing using the same chamber for every shot.
