Powder for 5.56 that meters well

Re Munson's post, Pat's said to use H335 data as starting data. I did this, and worked up a ladder test series of charges as I always do with new powders. In my M16A1 rifle with 55 gr FMJBT, I use 25.0 gr of WC844 and obtain a chronoed velocity of 3050 fps.

Remember this is bulk grade powder not cannister grade, and it is imperative that you work up a safe and accurate load for each different lot of powder. These pulldown military powders have been safely used by careful reloaders for many years. It's not like these are unknown powders that came over in boatloads unmarked and unidentified.

It's always advisable to purchase a large quantity of this type powder so you don't have to rework a load every time you need a new jug of powder and receive a different lot number. I try to buy not less than 100 pounds of this powder or any other milsurp powder whenever I buy it. One load workup and you're done for many years.
