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.

Same results that you got. Have you shot some and have real velocity data?
