[QUOTE="FireFlyFishing, post: 2927494, member: 127412"] Hornady has a fantastic podcast regarding twist rates in rifle barrels. Highly recommend this podcast. In the podcast they mention bullet stability will INCREASE as it travels down range. I’m guessing this is what you are witnessing. The ELD bullets are very long and need fast twist barrels like the 7 PRC has. I suggest you go to a lighter bullet in the same make/model or try a more traditional bullet shape in that rifle. I’m guessing you’ll have more consistent results at varying distances. [MEDIA=youtube]B4GOxTa9TDE[/MEDIA] Also, stop trying to determine bullet drop without a chronograph. You’re wasting your time. Output data is only as good as the inputted data. [/QUOTE]
