Luggo Posted March 10, 2009 Share Posted March 10, 2009 I cannot seem to find the data for FMJ. The Hodgdon site provides data for 231 and a 115gr LRN, but not FMJ...can anyone help here? Thank you. Link to comment Share on other sites More sharing options...
WestWorld Posted March 10, 2009 Share Posted March 10, 2009 The Hodgdon site shows starting loads at 4.3 grains W231 with a 115 grain LRN and 4.7 gr W231 with a Speer 115 gr GoldDot Jacketed Hollow Point. JHP and FMJ are very similar when developing loads. Seems like a good place to start. Link to comment Share on other sites More sharing options...

I am going to have to spring for a good manual, my Lyman 47 just isn't much help. Thank you Link to comment Share on other sites More sharing options...
goneracin Posted March 10, 2009 Share Posted March 10, 2009 I have been trying to work up a good 231/hp38 load with 115's. With my 4.4 barrel sig 226, I just did a setup with 4.65gr of hp38/231 and that gives me about 1070 average. This was with 115gr Montana gold FMJ, 1.125 O.A.L. I am trying to find the best OAL for my gun, and ive also done one run with .1 less gr, and 1.100 oal that was pretty close to the same velocity. I would suggest starting with a bit less powder, and working your way up. Link to comment Share on other sites More sharing options...

I don't have to be worried about PF's or the like, just enough to knock a steel plate over and punch paper. Link to comment Share on other sites More sharing options...
