I was working up a production load for my XD Tactical (5inch) and I had a few bullets to try so I thought I would share the data in case it helps someone.
Bullet - Montana Gold JHP 125 gr
Powder - Titegroup - 4.0gr
OAL - 1.125
Federal SPP
Avg for three strings - 1118, 1119, and 1124
Lowest PF of 134.5 with an avg PF of 139.9
These had a high STDEV, not sure of reason, but they feel great and the gun loves them. Very accurate.
Bullet - Zero 125gr JRN
Powder - Titegroup - 4.0gr
OAL - 1.120
CCI SPP
Avg for two strings - 1134, 1123
Lowest PF of 139.25 with an avg PF of 140.4
The zeros felt exactly like the MG 125s and were just as accurate. I would let price decide this choice.
Bullet - Montana Gold JHP 115gr
Powder - Titegroup - 4.2gr
OAL - 1.120
Federal SPP
Avg for two strings - 1157, 1154
Lowest PF of 130.6 with an avg PF of 132.7
I didnt prefer the way the front sight came back with the 115 over the heavier 125s. For whatever reason they are not quite as accurate either, but accurate enough for certain.
