I have 2 new rifles that shoot bug holes at 1 and 200 meters. I zero'd at 100m and get 3" drop at 200 and 16" at 325m. 108 eldm 2950 fps.
both guns do this. I don't understand.
 
That’s exactly what they should be shooting. I ran a quick trajectory for that load and bullet, but didn’t change yards to meters, just because.

First off: 100m = 109.4y, 209m = 218.7y, 325m = 355.4y

Here’s what I got:

It looks to me like those drops are dead on.

2.14 and 3 and 12.14 and 16 seem significant to me as far as bc numbers are concerned but hey I just wanted to point out on paper they don't match very closely, sure... I can true, but the numbers don't seem close to what the book says they should be and that is why I asked. This was paper not steel. Thanks

You are not reading the solution chart correctly. It is in yards, not meters. Your 16" is at 325 meters, which is 355 yards. Go down the chart past 325 yards to 355, or 350 and 375, and you will find it should be about 16"

you are at 219 and 355 yards on that chart.
Almost exactly 3” and 16” drop by the ballistic calculation.

See my original post.

This is correct. And at 200 meters or about 219 yards, the drop is exactly 3”.

I think that you need to change the settings in your ballistics calculator to read in meters and not yards. I didn’t change mine for this exercise and stated that. Sorry for your confusion.
