So for those 22 samples, Precise Load predicted velocity was within 27 fps average of what the actual shooting result was. If you take out the two "weirdest" results (44 mag and 450bm) the spread between PL and reality shrinks to 8 fps

Bartell approved!

Holy Smoke! Thanks for sharing. I will eventually post some of my load data Precise vs GRT vs Measured but currently do not have access to my reloading room.

I have noticed so far that my 308 loads have been predicted well by both simulators, while my 243 loads have not. I think that may be related to me playing nice with the 308 but stepping out of bounds with the 243, however I cannot say for sure.

My base 6mm GT load is high by 132fps in "Precise Load", so not useable. QuickLoad is low by 70fps.
