This has been asked before but i was hoping maybe some others have since worked on a solution or come up with additional suggestions.
Have bought some missouri cast 135s, bhn 18, W/O gas checks. brad says to keep them between 1600-1800. trouble is , i cannot find any data specific to a 135 cast. i have the current lymans, hornady, speer, etc etc, and none of them carry any data for it. i've been told that some of the older manuals had cast data that did specify some loads for either a 135 or a 140, the data that could also be used. I DO NOT want to use checks; some of these bullets are more expensive than shooting jacketed and if thats going to be the case, why bother shooting the cast to begin with. I was thinking of a test load of 5744 at about 17 to start. h4895 was another possibility about 21grs. Is unique a possibility here ? Hodgdon would NOT recommend any other powder except trailboss or h4895. Anybody go this route before.? Any suggestions or help would be greatly appreciated.
