Does anyone know how to supply parameters to the "Selected Propellant" interface in QuickLOAD that would characterize SR4759? I want to output pressure values that bracket the point of obturation for SAECO 356 without launching significantly over 2200 fps from my .358 Hawkeye.

The best I have done is to select a powder that is closest to SR4759 in burn rate and adjust the propellant record file up or down to match the velocity you have achieved with the SR4759 and then save it to a new powder file.So you will need to chronograph some of the SR 4759 loads to do this.
Sorry if I am not very clear in my explanation,but what you are wanting to do is doable.

I know it's doable, I was hoping someone had already done it so I can load up some rounds tonight.

Thanks,

I'd like a profile for 7383 too. Be nice to have some predictions on it.
