38spl vs 9mm loads ???
I've loaded thoustands of 38spl simi wad cutter & jacketed rounds. Just got set up to load some 9mm and was comparing powder loads.
I was surprised when I noticed the 9mm required more powder than the 38spl
My manual calls for:
38spl 158g Cast Lead w/ HP38 powder, start 3.1g to Max 3.7g of powder
Pressure =14600 cup
38spl 125g jacketed w/ HP38 powder start 3.8g to Max 4.8g
pressure = 14100 cup
9mm 115g jacketed w/ HP38 powder start 4.7 to Max 5.1g of powder
Pressure = 28100 cup
What got my attentsion was my first drop of powder into the 9mm case filled it more than 50% full, so I've stopped until I hear some opinions from you guys, what do you think, I've always trusted my manual but this makes me scatch my head and pause.
