This one is kind of interesting guys.

On Saturday I shot a bunch of 5-shot groups to gather velocity data for my .58 GM/TC Hawken. For consistency, I used weighed loads that were the equivalent of 105 grains volume in my TC U-View powder measure. I shot GOEX FFg, GOEX FFFg, Jim Shockey Gold FFG, Triple Seven FFG, Pyrodex Select RS, and Pyrodex P.

Here's the data chart.



And here are the targets.













The Pyrodex P absolutely DESTROYED the patches. I found one wrapped around one of the wire "v" shooting guides on the chrono. All that was left to it was a wad of threads. That accounts for the total loss of accuracy and wide variance in velocities. However, I'm pretty sure that on the third shot on that target I failed to seat the ball after short starting it. (Got distracted swatting flies and wiping sweat.) Fortunately, it did the barrel no harm.

I was quite surprised to see how close the velocities were between GOEX and T7 in this barrel/caliber/load volume.
