Is Strelok app any good?

I only had 20rds with that load for that day. Did 3 groups, one 5rd group at 100, one 3rd group at 200 and same at 300. Groups were mediocre at 200 and 300, 3" at 200 and 3" at 300. At 100 all were touching.

Nothing wrong with 3” groups at 200 and 300 out of a hunting rifle.

I’d probably just try it again.

To repeat those results, the bullet has to be going an actual 2700-2800 FPS (which is inconceivable) or else your range distances are out by 50-75 yards or more.
 
There is a function in strelok that allows you to verify the data output. I haven't used mine for a while but you input your range, velocity and the actual group position on paper and it will hone in on your actual data. Basically strelok gives you a good estimate and then you can use actual data to make your dope very accurate. Strolok "should" then revise its data to meet yours. Hope what I said makes sense lol. I haven't used that function myself so I don't know how accurate it is.
 
Are you reading the vertical corrections in inches instead of clicks/MOA/mils maybe? It's not drop (inches), but vertical corrections based on your zero to those longer ranges. I don't even use that column...just the MOA depending on scope I'm using...I just want to know how much I need to turn the turrets.
2.28 at 200 and 8.98 at 300 is how high at 100 your POI is vs your POA...I think, or it's how high you would aim over your target at the given distance with a 100m zero (holdover)...that probably makes more sense.

Maybe your on to something. This was the first time I have ever used an app.

The reason I ignore the inch column is that it messes with my head calculator if I think about it too much lol. Just the MOA/clicks/mils, whatever type scope you are using...use what it says there and it will be accurate. I've used it out to 1000m shooting targets from 700m-1000m going back and forth, used the reticle holdovers, the app works well.

I've never used an app or really any ballistics calculator but if I'm reading your posts right your actual drop on paper with no adjustment is 6" at 200 and 13" at 300. regardless of what the app says that is not right. If I'm reading this wrong then as suggested input actual data and see if that helps.
