Here are some early 10mm JHP factory loads. I think the Remington is quite rare. It was introduced in January 1989, with a listed velocity of 1340 fps. Pretty stout for a 170 gr. JHP, and didn't hang around very long. The Winchester is actually weaker than the Hydra Shoks.

Very cool, I bet that rem load is flashy too.
Thanks for sharing.
The Remington consistently graphs 1300 fps out of a Sig Legion. I need to graph the Winchester; it might not break 1000 fps.
