As title says anyone have the FPS formula if you've tested rifle out to multiple distances and have dial up data? I know it's out there.
I've run both Caldwell and Magneto Speed on a 17gr Bullet over 4600. Magneto only capturing velocities half the time with crazy 500 fps jumps than giving Error 5. Caldwell captures velocities maybe 1/3 of the shots but numbers are more true to load jumps.
I've run load development through QL and GRL that gives me a good window. But I want dial up numbers.
Thanks in advance.
