Sterlok 22lr questions

[Jonathan DeBoer]

I recently downloaded Sterlok Pro. I was wondering how to use the multi bc function to make a custom curve. I don’t have a chronograph although I have considered getting one. The bc on the box (.172) this is for 50 yards I believe. I have shot at 100 and 150 yards and measured the drop from my 50 yards zero, at 100 yards the bullet dropped 18 3/4 inches and at 150 yards it dropped 26 inches. I’d appreciate any feedback on how to best true the round.

Just seen your other post, you have your drops in inches instead of centimeters.

I just shot targets in 25 yard increments to 300 yards and recorded the dope, then adjusted strelok till it matched my actual dope.
