I looked in my main load data book here at the house for the AR-15 and I have a small correction. For my Arma-Lite 180 the Win. 296 was the best powder. For my AR-15s the 748 was the best powder. A next best powder for the Colt AR-15s BLC2 was the most accurate. I have 7 AR-15s (why I have no idea) and they liked the 748 and BLC2 as far as accuracy is concerned.

Slightly off AR's ... 748 works well in .30-30 also

- I use 748 in both and in my 30GNR as well. (nm) - drdougrx, 2025-12-12, 06:10
