Thanks shootist. With your reply I can try to explain myself in that area a bit better. Thanks to both of you for reaching out....
I am trying to take what I know and implement it into QL to get as close as I can to accurate pressures that QL can offer. I certainly dont know everything about the 44-40 but what I do know I have acquired from other guys that do know. Kind of like gathering info from several well knowledgeable guys and trying to put it into QL. QL's default 44-40 info is correct for the 44-40 of the past but not of the present....as far as the ".428" cartridge/bore information used with soft lead bullets of years past. You already know I suffer from trying to put what's in my head down on paper so to speak...referring to texting/typing my thoughts.
My 1894CB Marlin's barrel should use the 44 magnum measurements in QL while my original 1888 Marlin uses the original 44-40 measurements.. .426, .427, .428 of yesteryear vs .429 and .430 bores of today......still refering to cat. II strength rifles, not the weak action of the 73".
I have noticed a lot of information that I would just like to confirm is not "garbage in" as I have read in years old postings. Playing "catch-up" is not easy.
For example; QL uses the volumetric data of 40.00gr while my measurements in win, rem and starline brass run between 41.20 in win/starline to 42.40 in remington brass. All of these ever so slight inaccuracies can cause the pressures of my loads to range from 18,000psi to 23,000 psi, not to mention outside air temp.
Sometimes even if no one replies to my posts, re-reading can energize that lightbulb in my little brain. I even made a little form to help me keep my data straight when entering it into QL. So easy to make mistakes.
I have several other examples of what data is correct. QL uses 15,954 PSI as a 44-40 pmax while SAAMI 2015 data shows 11,000 PSI.....there maybe something there I am missing. All of these little things I am trying to learn in order to feed in "good info" to get out "good info" rather than "garbage".
THANKS!!!

So my goal is not to make a 44 magum out of a 44 winchester but to find the perfect load for my rifle :-)
Quickload is a guide. A great guide for sure and I use it regularly and feel much better informed for it. Whether I am or not is another thing altogether.
As a young man I because very absorbed with HiFi. This was in the days when it was a difficult hobby. One quote I recall from one of the many HiFi magazines (pre internet!) was to the effect that the serious hifi enthusiast would own about half a dozen test records and three LPs of music. They spent more time on the test records that with the music, and when they listened to the music, the were actually listening to the silence between the noise. It is beginning to sound like you are doing the equivalent, which can be great fun. Just a comment really.
You are clearly very well educated in the vagaries of Quickload and internal ballistics. You shoot well and often, by the sounds of it. I can't quite figure out why you are posting on this forum rather than one which is more specialised, one where you may well get answers that are more in line with your questions. Don't get me wrong, I welcome your input but you must be aware by now that there doesn't appear to be a source of info on this forum to match your knowledge. Perhaps you might spread your discussions wider. I don't doubt you have much to share.
