Got some range time in today behind the chrono testing some loads. Im looking for a load with BullsEye under 180grn Precision jacketed bullet. Want to get down to about 130-135 PF since Im shooting .40 against the 9mm guys in IDPA. After shooting today, figured out that I started way too high on the charge weight. I started at 4.4grns up to 5.2 grns at both 1.135 and 1.125 OAL. I shot five rounds at each charge and this is what I came up with.
4.4 grn BE OAL 1.135 Avg Vel 847.4 PF 152
4.6 grn BE OAL 1.135 Avg Vel 871.2 PF 156
4.8 grn BE OAL 1.135 Avg Vel 915.5 PF 164
5.0 grn BE OAL 1.135 Avg Vel 940.0 PF 169
5.2 grn BE OAL 1.135 Avg Vel 969.4 PF 174
4.4 grn BE OAL 1.125 Avg Vel 862.8 PF 155
4.6 grn BE OAL 1.125 Avg Vel 885.6 PF 159
4.8 grn BE OAL 1.125 Avg Vel 902.6 PF 162
5.0 grn BE OAL 1.125 Avg Vel 944.2 PF 170
5.2 grn BE OAL 1.125 Avg Vel 967.4 PF 174
Like I mentioned above Im looking to get down around 130-135 PF. Any one shoot this combo of bullet powder and have any data on it. Im thinking I need to start around 3.5 grn and go up from there. All loads had wolf SPP and mixed head stamps, out of a Glock22
