Since HP ammo has been so hard to find, I decided to roll my own 9MM SD rounds. Finally got a shipment in of Remington 124gr JHP. Did my research and started with 4.4 grs of W231, loaded to an OAL of 1.123. Loaded some at 4.4, 4.6, 4.7 & 4.9 grs. Shot each progressively, looking for pressure signs. Got through the 4.9 batch with no adverse results or signs. All loads shot to POA. I think I'm going to adopt the 4.9 gr loads as my new SD round, loaded into virgin Starline brass. I don't have a chrono, so this is the best guestimate I could come up with. Any thoughts, ideas or suggestions? Thanks.
