This evening I was loading some 5.56 on a Dillon 550 and about every 100 rounds I'll drop 4 measures into a cup and weigh, just to be sure the measure is correct. I'm loading 25.0 gr of H335, and if I remember correctly the test loads for 4 drops were 100.0, 99.8, 100.2, and 100.1 in my loading 500 rounds of ammo. It doesn't get much better than that.
By the way if you load a lot of 5.56, check out Pat's Reloading. They have 8 pound jugs of pulldown WC844 powder which is the same as H335 for $85 per 8 pounds. It's cannister grade powder but the price is sure right.
Not questioning you, but how do you know it'd the same as H335? Is that the data you are using?
