OK here as in many places it seems I can't find the right word combination or the search engines are broke. Spent some time looking for feedback on the two powders in the title and find very little. I am not going for competition I want basic good accuracy and have a variety of stock AR15's 16" and 18" barrels. AR-10's are 16" and 20". Again these are stock and not altered for accuracy nor any special match barrels. Twist rate is standard Ruger 223 and DPMS 308 which I do not remember off hand. My longest shot on my land is 200yds or less. Mostly 62 grain on the 223 and 150,180gr on the 308. Bullet weights may vary at times depending on what I can find but I have these on hand now and will begin reloading soon. Also the brass is mixed and once (or more I am sure) fired.
