RMR .45 230gr. FMJ RN test results

[vaalpens]

I have done some more testing with the RMR 230gr FMJ RN bullet on Friday. This time I decided to try some Longshot just to see what results I would see since it is not really known as .45 acp type powder. The velocities seems lower than published, which could just be the 4.4" barrel, the colder temperatures and the COL I am using. It feels/seems that I should be able to go with higher charges if I want to try a few additional loads. The accuracy wasn't great, but surprisingly consistent from min to max. Not bad for a powder that is not supposed to work well in .45acp.

Following are the test results. Testing has been doen at 15yards using a rest and a scope that was not zeroed.
