You loaded 20 rounds each from min to max @ .10 increments......you the man!

How are you metering the powder? How does the stuff flow?

Yeah... The loading data is a little far and between.So I figure would start low end and go up to max .10 at a time, with 20 rounds each, stick with the standard OAL, the only variable would be the charge.I may not shoot all 20 rounds of each.I ran it through a Redding BR30 powder measure just check throw to throw and it's not that bad, also a RCBS Uniflow with good results.

BR30 set to 21.0g895.020 throws ranged from 20.9-21.1 with even consistent motion actually less than that. But for this I weight every charge and used WCC cases only. What's funny I posted in here on another post about using my Rock Chucker press, this is what I used to load these. I'm hoping that I can go and shoot these this weekend. I will first try to go to a range, if busy will have to go to friends place where I have the time to test them out. I will focus on 5.56mm first then work up some in 7.62mm, don't get me wrong I will be shooting the M1A this weekend also.

Could of got more a friend picked it up for me

I have attached some places that talk about it

this is what was posted pic of it,from another site (looks like H322 or H335)

If I can get some more, I will buy the case and if I see it some where I will post here for sure, I have my eyes,ears open
and will talk to my friend, should be home this weekend.

Handloader Magizine did a write up on it in last months issue. They gave it good reviews. Where did you find it, I have been looking but no luck yet.

IMR 8208 XBR IS NOT the old 8208M surplus powder.

Back in the 80's, a major lot (5000lbs) was repackaged by Thunderbird cartridge company and labeled T-32. Yet another was repackaged and labeled simply 8208.

IMR 8208 XBR is manufactured by Australian Defense Industries (ADI).

Dupont IMR 8208M was the old powder.. loaded in early ball m193 rounds ...this is not to be confused with the new powder
