While experimenting with HP diameters and how they expand in Ron's test with 35gW/50gV BH209 - my bullet occurred much father downrange than I had imagined. I started wanting to know what his test were representing with other bullets he's tested - Distance, with respect to Velocity & Energy?
Previously, I averaged the BH209 data for all 250gr & 300gr bullets listed within each load listed; 84/120, 70/100, 56/80 respectively. So, that's the vertical lines indicated on the corresponding Velocity & Energy graphs along with Ron's 35/50 grain load (light blue).
One can look up Ron's vast test and see exactly how their bullets are performing and at what distance - Ron's testing is with 2 loads 56/80 and 35/50 - REMEMBER, not all bullets passed his 35/50 test.
Maybe all this might help someone understand what their bullet is doing.

That's interesting graph work. Thanks for sharing.

Here is a list of Ron's 35/50gr test, if it helps.



I expanded the graphs with some other loads.
Interesting that with max loads of BH029 a 300gr will overtake a 250gr in Velocity well before 200yds.


Energy: note how the 300gr overtakes both 250gr loads regardless of MV around 300yds and all 3 lighter bullets are nearly identical at 500.

And the 300gr energy exceeds the 250gr through the entire range excluding the 4 pellet load which is not a typical load for most people. Even the Ultimate guys probably find that load to not be the best in accuracy.
