Sharing some 10mm chrono data

[Duvel]

227 loads, to be exact

Mostly because I really enjoy the hobby, and to build a workup baseline for MY gun.

Some loads are below / above book values, some have no published data. What proves safe in MY gun may not in YOURS. Use the information linked below at your own risk!

It's also important to note that most loads were NOT tested (Gen 4 G20) with the stock barrel.

CAUTION: The following post includes loading data beyond currently published maximums for this cartridge. USE AT YOUR OWN RISK. Neither the writer, The High Road, nor the staff of THR assume any liability for any damage or injury resulting from use of this information.

Of ALL the loads the 135 11.2gr Powerpistol has the most bark

l love the Power Pistol, it's my favorite Tokarev powder and is a top performer with the 9m and 10mm. I also use it in 357 Magnum with bullets up 158 grains where it gives 95 percent of the velocity the slower powders give you with much smaller charges.

I like Powerpistol for the lighter weights / lead coated.

#7 & Longshot for, well, everything

Thank you for posting - that is a wealth of information. I've just started reloading 10mm and this will be super helpful!

Thanks torchroadster!

It's been been fun, but I'm at a point with many of the loads that continuing without some method of accurately measuring pressure is asking for trouble.

Only thing I come up with (short of sending the loads to a lab) is a Pressure Trace and a Contender.

Off to find a barrel
