I use it in my 223's with Barnes 62 grain bullets. Very accurate!!
Ditto on Varget (26.2 gr.)and the .223 with 62 Barnes, very accurate and a deadly hog load. Also found a 62 grain Hornady HP sold in bulk by Midsouth that shoots even a little tighter groups than the Barnes at less than 10 cents each. My .308 40X shoots very excellent groups with Varget using Hornady 178 BTHP, Sierra 168 MK, and Hornady SST 165, all with 44 grains Varget. I used to own a 6.5 Creedmoor that shot best with Varget and 120 Barnes or 123 Scenar.
