I just worked up to a max load of H4895 for a 225gr bullet listed by Hodgdon 46.5grs. My partitions with just .020" leed is a 2430 fps and the Sierra iabout s the same. The 225ge hawk RT is at 2320fps with the same 46.5grs. The hawks I pushed deep in the case too keep the load dencity up. The OCL is 2.685 with about .070" leed. The 200gr spire point is 2.665" OCL so I can still push the hawk back some .020" for tunning the load for accuracy before it hit the bottom of the neck.
I suspect I can use more powder (.5-1.0grs) because the primers have very round edges just like new primers and there is no issue with extraction.
How do the hawks pure copper jackets usually compare with gliuding metal jaketed bullets? They seem to have the same bearing surface as the 200gr spire points and mabe less than the 225gr partitions. What I have is more case space and more leed length. I suspect my pressures are lower than with the noslers/sierra's. These are the .030" jackets choosen for WT Deer I think moose and elk may need the .035" jackets.
