Using actual case capacity, and actual bullet length/weight... QL does what it does best:
get you safely into an actual data regime from which you adjust burn parameters.
(My data only. YMMV . . . so loader beware)
EXAMPLE:
350-LEGEND/Win Cases (36.7gr H2O)
LEE 358-200RF cast Lyman#2) (actual 195gr/0.854")
Norma 200 (full case/27.4gr) default QL parameters
OAL: 2.17"
Predicted 15" (rifled length):
1,918fps/39,498psi
Actual:
1,980fps/43,400psi (LABRADAR, and V-cubed ratio as wet thumb before I adjust burn rate)
Actually, I can't complain.
QL is an engineering tool
