hotrod;
Thank you for telling me about the PF thing, it works out better than using recoil and has open my eyes to a new way of looking at loads.
Here is some data that I worked up on my M49 snub nose J frame with factory and reloads.
You will notice that you have to choose between energy or penetration when matching loads with the same power factor, with the 38 special around 94 to 96 PF and +P ammo starting around a PF 105.
148 hbwc Remington 640fps......PF 94
reload................ 775/197me ...PF 114
110 SJhp Winchester 875/187 .....PF 96
Hi-Vel .....................996/242 .....PF 109
125 Jhp 38 spl~ Nyclad 830/191 ..PF 103
Standard 38 +p .......... 880/215.. PF 110
135 Speer factory ......... 860/222...PF 116
158 LRN Federal ........... 648/148 ...PF 102
Reminton FBI Lhp .........861/260 ...PF 136
Many say the 148 lead is a better light SD bullet but looking at the energy of it and the 125 Jhp, along with the PF figures, I would say there might be two bullet choices before going to the heavy 135 and 158gr loads. I would not pass on the 110gr either, I know that I would not like two of them rattling around in my body.
