Jerry, You might try over on Steve's pages. There is data there for 180 grain and 155 grain in 7.62x39. You can start with the 180 starting data and work up. The load will probably end up somewhere pretty close to the 155 start loads assumming these are jacketed loads and the lead bullets generally generate lower pressures. Note an assuming and a generally in the same sentence. Start low and work up. RD
hmmmm...i have the .312 155 2r regular lube groove version , using #2 alloy mine weigh in at 154 lubed and checked leaving me to wonder what alloy you're using , sadly i havent tried h322 with this boolit because alliant 2400 rocks !!! here's a good thread on the m-43 round ( the original piece was written by the guy who designed both boolits ) http://castboolits.gunloads.com/showthread.php?t=13453

usually what happens is there is more lead than tin or other metals that cause some cast to go heavy. i have heard of molds casting at a differant weight than what it says it is.
i have a lee 2 cavity 215 grain mold that with wheel weight, it consistantly cast at 210 grain.
unless some one has made there own load for the 7.62x39, the heaviest published load is for a 150 grain- at least that i have in my books. i havent seen a heavier bullet in factory loads either
my 350 grain 45/70 bullett will go to 360 grains once a gas check and lube is put on it- thats with the cast bullet at 350 grains before lubing and sizing
