Mariodave,
I use W748 and H335 to load my 62gr/SS109 bullets. As I was told awhile back, there is no way to get the exact factory recipes for duplicating loads. I suggest you start at 10% below max for same weight bullet and work up!
I have a Speer book that lists a 62gr bullet, so when I get home, I will post that data for you.0 -
i have exact mil data. on the ss109 5.56 m-855 it calls for
26.1 gr. of wc844 . this is supposed to be about 3025fps 78 ft. from muzzle..
i persoanlly have some of these powder. i use 26.0 gr. of the powder i have.. its a little slow. my averaged 2760 fps... its only a quide line. lots to lots required change. they vary in burn rate...i am going to bump it up for my next loading.
the wc844 is very silmilar to w-748 and h335 like the other man Laylandad stated
besure and start at 10% below max and work up
the data came from tm-43-0001
