need 260 load for rams with H4831
Does anyone have a recommendation for a ram load using 142 MK and Hodgdon H4831 powder?

I am using IMR 4831 which should be faster than H4831. I am using 42grains wiht a 210m primer and getting 2800fps in a 26" barrel with 139gr Lapuas. This is not max pressure but is slightly compressed because the reamer was designed to throat 139-140 bullets to short action mag length. I would start at 40 grains of H4831 and work up from there watching for pressure.
