I'm not saying that ball powder with the #43 primer was as good as IMR 4895, what I'm saying is that there is a known delay in ignition issues with WC846 with military primers. http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA341390 The recommendation was to standardize to WC846FS (Flash Suppressed) as it showed more consistent ignition with either the #43 or #34 primers. The report states that case fill was critical in getting proper ignition with WC846.
