I shot with the Glock because it shows pressure signs before the rest of my 10mm choices.

No smiles - case expansion .433 for the hottest load.  It looks like there is more room for powder, and I'd say that these aren't max yet.

They say BE-86 is flash suppressed.  There were some fairly impressive fireballs with these loads!

Thanks Greg great range report and interesting numbers...
Matches the Sig Sauer 1800 FMJ loadings pretty close, my testing of the pulled and reloaded showed

Glock 29 21lbs Spring  velocity     1178    case expansion    0.4315"
Glock 20 22lbs Spring  velocity    1250            0.4315"
Glock 20 22lbs Spring  velocity    1260            0.4315"
S&W 1006 22lbs Spring velocity    1276            0.4265"
S&W 1006 22lbs Spring velocity    1286            0.4270"

BE-86 is a very useful powder.  I don't feel the top load tested is anywhere near a maximum load.  I'll still need to notch it up a bit more, but I think it would be wise to use virgin brass.  I'd like to know what is possible with this powder and see how it ranks with 800X and Longshot.

The Labradar data is easy to report.  I just need to copy off an excel file on the SD card and paste it here.  Pretty sweet setup.  80 rounds of 10mm, 50 rounds of 9mm in 14 series, all in an hour and 10 minutes, and that is picking up brass between series.  It took less time that cleaning up the 3 guns I got dirty

Great range report Greg. I just purchased 8 lbs of BE86 a couple weeks ago but haven't had time to start loading for it yet. I'm anxious to see how your further development goes.

[Geeman]

More steps up.

My word of warning, I'm above any loads from any book.  Work your loads up yourself.

Case expansion .433" on the 9.3g load.

Its getting there.  No indication of a smile yet.  My slide stopped locking back on the last three shots, so I have to figure out what happened there.

I'll keep on stepping up.  Starting to feel like a real 10mm load, but there seems to be more room.  I thought I'd be pulling some bullets, but all went well up to this point.

Good 10mm powder.

Thanks again Greg, for another great report.  Yes I would have to agree that the BE-86 is a great powder for the 10mm and many other cartridges.
