Greetings all. I recently tested some 10mm loads I worked up and collected some velocity data.
I was using twice shot Sig brass, CCI LP primers, a ladder workup of Accurate #9 with the top being a mildly warm load of 13.3 gr if I remember correctly, and pushing a 180 gr flat point plated bullet around 1250 fps on average.
1250 fps is listed on the box off bullets as the max velocity.
What puzzled me a bit was the extreme spread on velocities. One series was like 90 fps. I wasn't getting sooty brass at that point which seemed to indicate a good burn, accuracy was acceptable, and I had no malfunctions.
I guess I'm just wondering if pushing a plated bullet to max recommend velocities could cause the ES to climb.
Or are there just too many variables at play to answer this? I was thinking about trying this load in new brass to see how it works.
