Quickload Help - 9mm

[tinhorn97062]

Can anybody run a couple loads for me through Quickload software? I’m interested in seeing the predicted change in pressure/velocity as the OAL changes. Below are the inputs:

9mm mixed brass (mostly Win)
124gr Hornady XTP
Unique @ 5.0gr
OAL: 1.060

Same as above but with the OAL @ 1.100

At QL's suggested COAL of 1.169 they show the 5 grains Unique giving 91% fill, 26.4k psi, PMax of 35k psi
-- at 1.1" COAL they show 111% fill and 35.5k psi
-- at 1.06" we have 128% fill and 44.8k psi

Well that’s pretty interesting, with the 44.8k psi, since that specific load came right from Hornady’s published data- 1.060 OAL, Unique @ 5.0gr. I thought the pmax for 9mm was 35k psi. Any idea why Quickload would return a value that is considerably over the published pmax for the cartridge?

You can see the result, but pressure is marked RED and a warning text will follow!
