On Monday I tested another few loads with the RMR 230gr FMJ RN bullet. There are still a few additional powders I want to test, but I am slowly but surely adding some additional load data points for this bullet. The chrono data on Monday was all over the place and is possibly the reason why the velocities are a bit lower. I expected it to be closer to the Sport Pistol loads, but it is what it is.
The following test data was gathered by testing at 15 yard using a rest and a scope that was not zeroed:
