Hi,
i just picked up an 8lb`er of MP 411 from American Reloading. its supposed to like wc-844 which in turn is supposed to be like
H-335. wanted to know if anyone has used mp 411 and/or wc-844 to load 5.56 with either a 55 or 62gr boolit?

i know how to start at 10% less and work up ( done it for yrs) but i just wanted to know if anyone has a load less than max
that would give me a start point? using bbl lengths of 11, 16 & 20in.

looked up some info from several on line data site including loaddata.com. what i have come up with so far is an
avg. of 25.0 25.5 grs for a 55 & a tad less for 62.

thnx.

My plan was to start at 10% less than H335 starting data.
