115 gr 9mm RN FMJ
Difference in Hornady and Precision Delta is length of bullet;
Hornady .5400
PD .5650
This is the only difference I see in the two bullets.
With Hornady I was using 4.5gr of Win231 (this is mid range per Hornady 9th) with a COL of 1.100 (this is per Hornady 9th)
Can I use this same data with PD with a COL of 1.350? Am I thinking right or way off?

PS: I am using this for plinking and self-defense practice.
