Can somebody with Quickload enter some data in so that I can compare it to what my Quickload Version 3.9 is getting. I am getting some strange results.
Cartridge 300 PRC
Bullet Berger 220 LHRT #30486
Cartridge length 3.700
Barrel length 30"
Maximum case capacity overflow 95.6 (Hornady brass)
Weighting factor .50
Powder Hodgdon Retumbo 76.0 charge weight (Filling/L.R. 94.0%)

What Pressure (PMAX) and Muzzle Velocity are you getting with this data entered?
My results are:
Pressure (PMAX) 40,806 psi
Muzzle Velocity 2708fps

Thanks for the help.

I'll run that as soon as I get home. I'm interested in the results because I get strange results in my 300 PRC loads in QL using N570
 
Here you go....

Same results that you got. Have you shot some and have real velocity data?
 
Thanks mtang45. Your results are exactly the same as my data. Just loaded up some rounds and need to get out and see what kind of velocities compared to the QL.
