Help finding ballistic coefficient, is it possible?

[bigdawg86]

I purchased these bullets a while back for a cheaper target load when I am shooting at "closer" ranges. I just purchased my scope and I am going to be running my loads through my chrono, then a ballistics calculator to figure out bullet drop etc... problem is, what's the BC on these things? Any help would be appreciated.

You could just shoot them and find the actual drop instead of a theoretical drop...

Sierra makes a similar bullet. As a rough guess I'd say yours are around a 0.350 bc. They best way to get the actual number is contact the manufacturer directly, or chrono and shoot them to find your actual drop. Then you can reverse calculate your bc.

The Remington 120gr PSP is 0.324 G1
The Sierra 120gr PSP is 0.350 G1
The Speer 120gr SP is 0.392 G1

It's going to be somewhere in that range...

Go shoot it at distance and see what the drop is.
Chrono some too and gather your weather conditions.
With that info, you can backwards calculate the actual BC by trial and error using a ballistics calculator.
