Hi All,
Trying to model the performance of my 33xc (30 inch 9t, 300 OTM, Catridge Lenght 4.332, 111.5 gr H1000). Predicted MV 2941 fps, actual 3064 fps.
Case H20 139 gr.
Cross sectional bore area 0.88691 sq inches.
The only thing IMO that can cause this variation in prediction and actual performance is Heat of Explosion. QL us using 3630 kj/kg. Are there any other folks who are using QL and can confirm what powder "Heat of Explosion" number they are using for H1000 and are getting accurate results?
Any suggestions on how I can get this QL to match reality, will help.
Harjeet
