Just wondering if someone could or has chronyed factory federal Nosler Ballistic Tip. I made a chart and am trying to get a ballistics chart that actually does what the bullet is doing.

My current chart says at
1750 ft altitude
1.9 sight height
200 yrd zero
59 deg F (15 Deg C)
3650 fps

It says one thing but at 400 yards I'm actually at close to 19' of drop. (2moa plus the drop from center)

The lower right 3 shots were aimed at center target and then the next 3 that are slightly higher and closer to center I aimed 4 inches higher and corrected 1/2 moa left. Was gonna go another 1/2 moa left but ran out of light. There was a very slight breeze so I'm gonna wait for a perfectly calm day before messing with the left/right anymore.

Thoughts?

I used the federal ballistics calculator.

3 yotes with the 40 gr Nosler bt and very happy with them. All 3 drop in there tracks. A little damage to a small 12 lb yote at close range(52yrds) but no surprise at that close range.
