I'm trying to make a Production round for my XDm 5.25.I'm using Titegroup (for now), 180g X-treme FP, Winchester primers, range brass, with an OAL of 1.120". Here is what I'm getting using 3.6g of Titegroup. (15 rounds)
Average fps: 815.8
Average P/F: 146.8
Standard Deviation: 13.75
I have a pretty low charge now, is it safe to go to 3.5 or 3.4? Thats close to a 9mm load......
