I’m going back into my app to see if it lets me choose lh or rh.

SK Match was what he posted.

@Frank Green chicken scratch looks good and explains a lot about what I have seen on plate at distance. Updated your download with a screen shot. View attachment 8626307

Thanks for opening it up. I was in a hurry!

This also applies to CF guns also. Not just RF guns.

Faster twist rates can amplify this as well. Like going from a 12 twist to a 8 twist in the same caliber. For those of you that have ballistic calculators that's why the twist is suppose to be figured in to account for spin drift.
