I just picked up a new Savage 10 in 223, went to the range to test out some different loads. I was getting frustrated with it very badly! I tried many different ladder loads and so on , this thing just wouldnt shoot. So I decided to work up a ladder load with 52gr amaxs, 53 gr vmaxs, 55gr NBT, but all of them jammed into the lands. That worked out very well! It seems that this gun will only shoot jammed really hard, like .030" . If I jump .010-.050 it shoots shotgun patterns. Any guess's as to why? Measuring fired brass the shoulders only growing .0015 so it seems as tho its spaced right.
