Post by 30plinker »

Subject kinda says it all... looking for "real" published data for a 300bo load for the Speer 125gr TNT using 1680 or 5744.

I don’t think I have ever seen those combinations published.

I would just use Sierra data and adjust COL for the difference in bullet length.

The reason 1680 and 5744 with a 125 bullet load data is a bit harder to find is that, the performance is poor. Accuracy is acceptable, velocity is around 200 fps lower that other powders.
300 Blackout, not just for sub-sonics.
