I've been shooting a couple of Sigs in .40S&W and have worked up a load for the 180g cast to push them out at 1,140 fps. That is on the warm side I know but is close to or equal to some of the mild and moderate 10mm loads using the same 180g. bullet.

One of our sons has a 10mm and I would like to set up those loads to a reasonable yet warm level with the 180g like I've done with the .40 S&W.

Any load recommendations would be great. These 10mm will be out of a Glock 20.

Thanks again.

Longshot, just work up using your Chrony. Max is 9.5gr for 180gr jacketed. I stopped at 9.2 as velocity started to decline at 9.3gr.

Thanks for the recipe.

What was the reading on the chronograph with those loads and what shooter where they coming out of???
