Fired some loads for velocity and pressure checks.

Put 96 gr of Ramshot Magnum behind the Hornady 225 SP Interlock for a measley 2822 fps. That Ramshot burns like coal. I may have to reopen the old "One Time Coal Co." in Butler Co. PA and collect the bugdust for rifle powder.

89gr of RL-22 behind the same bullet produced 3068 FPS and may have been just a titch hot.

92gr of 7828 behind the same bullet gave 3094 w/no pressure signs

87gr 7828 behind the 250gr SMK produced 2877 and
88gr of 7828 and the SMK produced 2891

None of the loads were pushing any limits even for a 92 degree day.

Tomorrow I'll give her a cleaning and install the RSI strain gage and see how that gizmo functions.

ALl of the above loads were fired with a 1/8" flash tube installed. The whole idea of this testing is to see what kind of differences frontal ignition makes, if any. The RUM is a much better cartridge for this test than was the Win Mag.
