RE: 45 loads with 230RNL
I use 5.4 grs of 231 behind a 230 gr LRN 96/6/2 alloy. It works fine for me. Pretty clean. I can go through over a hundred rounds without having any problems from fowling build up.
I am not sure what gun you have, but that is the middle of the road load for 231 with that bullet according to the Speer #12 Manual.
