Took my 45 McRem Smokeless Muzzleloader out this morning. It's shooting around 2700fps shooting a Parker Ballistic Extreme with a BC of .250 (book BC is .267). I'm using the Strelok Pro App to calculate adjustment. My question is once I put all the info in it told me 9.5 moa adjustment for elevation and 2.75 moa adjustment for wind. I did not adjust for wind with the first three shot group to see the affect of wind. Elevation was still 1.5 moa low and the wind correction was very close to being right. I made the elevation and wind correction but added a little to the wind adjustment. The wind adjustment to me was correct however the elevation was off. I thought the BC was of but then it recorrects the wind adjustment also. I'm wondering if the chrono is not reading correct and if so do I back the info down in the app to get correct elevation adjustment?
