Note * – Always verify load data for yourself, starting low and working up in safe increments. Published data varies from source-to-source, and subject to typos and transposing errors. Additionally, internet posts such as this are someone’s personal experience.
Here were my results, 5 shots each at 50 yds:
23.2 gr – Avg 2673, ES 69, SD 28, 0.525”
23.5 gr – Avg 2717, ES 111, SD 39, 1.080”
23.8 gr – Avg 2775, ES 86, SD 33, 0.870”
24.1 gr – Avg 2781, ES 81, SD 32, 0.850”
24.4 gr – Avg 2874, ES 94, SD 45, 1.185”
24.7 gr – Avg 2914, ES 57, SD 29, 0.760”
25.0 gr – Avg 2939, ES 65, SD 28, 0.730”
25.0 gr – Avg 2930, ES 96, SD 35, 0.860”
A few observations:
- My best load (IMO) was 25.0 gr which produced a five shot group of 3/4” at 50 yds with an average speed of 2935. I think I will load it at 24.9 in the future.
- Ball powder meters very well. And burns clean, even shooting suppressed.
DISCLAIMER
The load data contained above was developed using specific components. Other components may not produce equivalent pressure or velocities; therefore, it is recommended that the user be familiar with the basic rules of reloading safety. If you choose to use any load data above, you are using at your own risk.
Always verify load data for yourself, starting low and working up in safe increments. Published data varies from source-to-source, and subject to typos and transposing errors. Additionally, internet posts such as this are someone’s personal experience. My recommendation is that you should always consult at least three sources of manufacturer’s ammunition and/or powder reloading data before reloading your own ammunition.
