11.3 / 2 = 5.65 . I think he just " typoed " incorrectly . To tell you the truth I really like " Accurate Powders " website . The main company is Western Powder , they own Accurate and Ramshot powders . You can spend your money on manuals , but I truthfully recommend you ck them out first , buy a # of one of their powders and have some fun . I don't / won't use bulkier powders in small cases . Too much chance of getting inconsistent charge weights . A couple of tenths variation in a big case , no worries . But in a small case , not so good, esp in something like the 380 acp . Remember , it's just a " short 9mm " cartridge .
Try taking a look at their website and consider their powders . They meter very very well (flow like water ) so you get very consistent charges which is very important when reloading a small cartridge like the 9mm , or worse the 380 acp .
