I found the same deal on my FCP-K .308 not ten minutes ago! I just sat down at the computer to find any info on it (& have a whinge) when I read this post, I've got .025 thou differance between front & rear of the action, sounds like it's more common than not, sure explains why I was 3" high at 200 yds & bottomed out the elevation turret on the BR nightforce (20moa farrell mount as well) looks like the front of the action might be bent a tad, may also explain why the front of the action dosen't touch the bedding block when torqued down to spec's,(200 yd grouping is rubbish 4 1/2" if lucky) will take it back to the shop I bought it from & see what happens, though in Aus. that might be interesting.
