I am working on setting up a 9mm load for my cast 124gr round nose. After reading though several load data books and sites, I saw that with Winchester 231 powder I should be somewhere between 3.7gr and 4.5gr. I loaded my first three sets (of 5 each) at 4.0gr, 4.1gr, and 4.2gr. They were all very accurate, but only two of the 4.2gr fully cycled (ejected) from my Bersa Thunder.
Has anyone else worked up a similar load? I am wondering why I read on several forums that 3.7gr-4.0gr will fully cycle. I am planning to load three more sets 4.3gr, 4.4gr, and 4.5gr to test. Would prefer not to shoot hot loads with the lead casts.
Any info would be appreciated.
