About the lightest 10mm bullets I have ever fired were 155 grains, and I tend to about 180 grains now days.

I'm definitely gonna order some of the 115s' and break out the chronograph.

I don't anticipate getting velocities that low. I'm known for handloading/reloading 'nuclear' loads. I surpassed the hot original Norma factory loads long ago. Then after the 1006,they'll be tried in the 6 1/2" S&W 610.
Some of my 'nuclear' loads,9mm 1600fps Beretta92,38sp 1400fps S&W 4",357M 1800fps S&W 6".

The Lehigh site is very interesting and worth looking at. They even list/publish load data(in PDF format).

I live about 30 minutes from Lehigh.  They gave me a tour of their facility a few years ago.  I got a lot of bullets for free during the tour.  Very good company for information.

I've only loaded subsonic 300BO ammo and their bullets work great on PA Whitetail.

Yeah, I looked on there loading data for the 115 grain bullet. The only powder they list that I have is Blue Dot, and the loads for that are around 200 fps less than the other powders listed.
