Litz tests to the transonic and averages the bc for the entire flight then publishes that number. It's too far. If I use his average bc I will shoot over a target at 600y. I have never tried, but am guessing if you use his drag curve it will line up.
@LibtardMcSocialist not sure why you need to be so aggressive. We are a home grown business giving everything we have to do this right. We have no intention of lying about our product, would be the worst thing we could do for business. We use the best material that exists, and do everything we can to make the best bullet possible. I never tear down or bad mouth any other bullet to try and make us look good. If you have used our bullet and did not like it, then post your results. I would be the most interested one to hear that.
The 177 is listed with a min twist of 8". If I were building a rifle to run it I would use a 7 or 7.5 twist. This would get the stability where it really needs to be. Most guys are running it very well in 8" twist some have trouble. It is a very long for caliber bullet, particularly for it's weight. Bullets than long get tough to deal with in some rifles.
