I do not douth your MV of 3476fps or your value of 2.5 inches high at 100 yards. 100 Yards is quite close to your shooting position and so the effect of errors is limited.
Taking these values and a G1 BC of 0.486 I got the following drop table:-

With values corrected for your altitude and temperature.
These values were confirmed by two seperate programs which only showed a difference of 1 inch at 1000 yards.
At ranges other than 100 yards, my drops are out of whack with yours. At 400 yards you get a drop of 10 inches and my tables show 6 inches.
Perhaps some thing you could check for is canting. This may be due to the scope not being aligned properly on the vertical/horizontle axis or maybe you are holding the rifle at a slight angle. Canting will cause point of impact error which increase exponentially at longer ranges.
Another thing to check is are the given distances correct. My tables give 6 inches drop at 400 and 10 inches drop at 450 yards. 10 inches is the drop you give at 400 yards. Perhaps your range measurments might be off.
If you email me at
[email protected] I will send you a chart showing the drops given above.
