[QUOTE="jdyoung, post: 2009181, member: 113391"] What I do: I always use factory rounds in newly acquired firearms, whether used or new. That way you are not breaking any Mfg. or previous owners rules in case it doesn't measure up. Measure those factory rounds and also get velocity when testing. Once I find the accuracy I want, 5 loaded rounds are sacrificed by pulling the bullets and weighing the powder charges and bullets. Once I know the charge weight, I enter the data ( caliber, case volume, bullet: COAL, bullet brand -weight-seating depth, velocity , charge weight etc), into QuickLOAD. With all those in the program, and the powder charge weight entered, I just change the powder brand and designation until the velocity I have recorded is shown. Now I don’t always get the very same velocity but I pick within 40 -50 fps of the velocity I recorded for the accurate factory rounds. Crimp is not included in QuickLOAD ‘s calculations, but is a factor in factory rounds, so I use a Lee Factory Crimp Die with an inch lb torque wrench setup on the press to vary the amount of crimp applied.
