10mm powder of choice?

[Dueling1911s]

I use Blue Dot for my heavier (never exceeding published data) loads. It has worked well for years and not once caused a problem. My data shows Blue Dot 10.5 grains as max load for 180 grain Jacketed bullets.

my speer book puts max load at 11.0 grains at blue dot with a 180gr fmj

but every book is a little different
