please help get QuickLOAD set up!!

[kenickie22]

I recently purchased QuickLOAD, and am having trouble getting it set up. I'm trying to get it set up for my 30 BR. I've changed the parameters that are obvious (cartridge length, case length, water weight, etc.), but I don't know what to do from here. Charges of H4198 that don't show pressure signs in my rifle are showing way over in QuickLOAD. I'm touching the lands using a Berger 115gr bullet. My cartridge length is 2.29" the case length is 1.515", and my barrel length is 26". My H20 capacity is 40.5gr. I'm using 10825psi as my start pressure (3625 + 7200 for bullets touching the rifling). 32.5grs of H4198 is showing over pressure in QL (34.2grs is showing over when I leave the start pressure at 3625psi). I've shot 34.7grs with no signs of excess pressure. Is 58740psi (the default value) too low of a max for this cartridge? What do I need to do to get it set up correctly? Thanks!!

Chris Long (aka Techshooter), has a good article on his website about tweaking QL to match your chrono numbers:

I'm not going to give you any advice on your pressure question, except to say, be careful. Just because you don't see the classic signs of overpressure, doesn't means you aren't there or beyond. I ran a 6 Dasher way too hot a while back and while I saw no overt signs of pressure issues, my brass was toast after about 3 reloads (the primer pockets were completely wrecked). Thinking back now, I feel pretty lucky.
