Didn't get to chrono the 9x25 Dillion but it shot

I worked up using .357 SIG dies. But they were easy shooting with light recoil and interesting the brass ejected to the left!? Kind of slowly they traveled over the top of the ejection port and fell right under the outstretch gun, nice, easy to find. I found some more load data for more domestic powders. My Unique load with the 115 gr. seemed mild and functioned fine. It was a little long for the magazine so I could only load three, but it fed. The OAL is limited to 1.25" bullet selection is notable here, a JHP or .357 revolver bullet would be more flat ended and OAL less critical. My 175 gr. FNGC is perfect and I should be able to run about 1400 fps., same as my .357 Revolvers. The other powder data I have shows 2400, H110, 296, AA 5-7-9, 4227, a delight. I'm running the G21 Glock with stock spring and 10mm mags under the Wolf G20 conversion barrel. Of course a G20 is drop right in.

The .357 SIG dies should work with no problems. I'll try to neck size and just bump the shoulder, sort of like preserving TC brass.
