I normally run Bayou Bullets RN 145gr over 3.4gr of Sport Pistol. I pickup a bunch of Bayou Bullets 147gr FP and used the same recipy.
I tried alternating them in a mag on day just for the fun of it; I couldn't tell the difference. All load and fire just fine. I load the FP now a little hotter and longer as a PCC load.
My two takeaways were, 1) FP cut better looking holes in paper and you can see them better, and 2) they work great in a bowling pin match.
