Thread: Difference between ballistic chart and real word results

I am shooting a 7mm08 17 inch barrel with handloaded162 Eldms. 41.5gr of 2208.

I have chronographed the load and have a speed of 2575fps which I thought was about right. Gun is zeroed at 100y.

I have just got a sew set of swaro rangefinding binoculars which when shooting at 400 yards showed a dial up on 7.5 MOA. Of interest was my strelok app showed the same.

Now when shooting my impact was around 6 inches high. 6.25 brought it back down to bang on. Only thing is for me to get the binos reading that MOA I had to enter a speed of 2750fps which seems a bit too fast.

Thoughts?
