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:
24.1 gr – Avg 2772, ES 75, SD 30, 0.725”
24.4 gr – Avg 2782, ES 81, SD 36, 1.000”
24.7 gr – Avg 2861, ES 128, SD 46, 1.370”
25.0 gr – Avg 2913, ES 127, SD 49, 0.750”
25.3 gr – Avg 2932, ES 45, SD 19, 1.320”
25.5 gr – Avg 2954, ES 85, SD 39, 1.350”
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 2913.
- Ball powder meters very well. And burns clean, even shooting suppressed.
