Hey POP QL Help

[steve4102]

Holy Crap, I must be doing something wrong! I plugged data in for 10mm Auto and what a shock. I compared QL to published load data and they are not even close.
For example Hornady #7 lists 14.9gr of AA #9 with their 180gr bullets. Quickloads puts this charge at 112,671 PSI.

Here is my QL data. What am I doing wrong?

Cartridge : 10 mm Auto (CIP)
Bullet : .400, 180, Hornady HP/XTP 40040
Cartridge O.A.L. L6: 1.260 inch or 32.00 mm
Barrel Length : 5.0 inch or 127.0 mm
Powder : Accurate No.9

Predicted data by increasing and decreasing the given charge,
incremented in steps of 2.0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !

Hey, POP, doesn't Quickload err high on straight walled cases? Maybe that would explain the difference, but that's a lot of explaining. What's the COL in the Hornady manual? A shorter one in QL could create those pressure spikes (and also the same in reality). Just a couple of thoughts.

 

[steve4102]

Hey POP, Take a look at PMax (Map) pressures QL has listed for the 10mm Auto (SAAMI). I am using version 3.4, my max pressure reads 327,525 PSI.

Yup same here...I just delete the last digit.....

Max COAL is 1.260"
