It's very close to current H322 burn rate... Just a touch faster... Or seems that way.. IMOP due to the smaller dense kernals... By way of a measurer one will get a bit more "hotter" load with LT-32 IF one sets the measurer the same for both H322 and LT-32... Use 322 data and start 10% reduced.
Don't forget about current Canadian AA2015........! The same powder as LT-32 just the burn rate is on the slower side, compareable to most pulldown lots of Dupont IMR 8208... Canadian AA2015 should be just right in the 6BR......
