If you want good results, it is for every cartridge, every rifle, and weather conditions. You will to calibrate to your chrony as well.Are these procedures a one and done thing? Or necessary for each cartridge ?
Welcome!!I'll stick to this thread as another has gone array! I've has this program for several years and I'm still trying to learn the in's and out's of a productive result. I've used published data for cross checking and some have shown way over pressure. Some loads are what I've used for decades without any issues, but QL states otherwise. I'm not sure what to make of it!
That's what I figured, thanks. In light of that, one almost needs to shoot one off to know how close QL got, am I wrong? So I have a load, and know velocity for that load, adjust the mess-arounds till everything matches , and then change, say, bullet? Then shoot, and repeat ? Just looking for safe starting spot with other components. For instance, a 285 ELDM and, say 24N41. That seems like it's going to be a x time investment, for positive results, at least for a cartridge that has little to no data available. Which is why I bought it. Hope I got all that rite!If you want good results, it is for every cartridge, every rifle, and weather conditions. You will to calibrate to your chrony as well.
What I do, I start with measuring volume of 10 fired cases in that rifle. Use the average in QL. Start with a known load, run QL, and adjust for OBT. Make sure this load is below book max. Load some, shoot and chronograph. Calibrate, and see what next load should be. Repeat as neededThat's what I figured, thanks.

Thanks. Ummm.... What is OBT?What I do, I start with measuring volume of 10 fired cases in that rifle. Use the average in QL. Start with a known load, run QL, and adjust for OBT.

There are QL experts here that will have better suggestions. It is what has worked for me. I consider myself an Amateur QL user though I have had it for years.
What he said to be sure?Thanks. Ummm.... What is OBT?
I'll try, cause I'm still learningif you have your case capacity, bullet length, weight and your oal. all set and you have set temp. and Ba. and your velocities are good or still low, but it says pressure is off the charts and from experience your primers and brass or even your bolt lift are saying something different lower weighting factor.
Appreciate the time you're putting in here. That's what I like about Len's living room.What I do, I start with measuring volume of 10 fired cases in that rifle. Use the average in QL.

Thank you, much appreciatedunsized, freshly fired with 2-3 firings to get case capacity.
