I too found Varget to work great in my 308; but when I tried it in my 223, I lost quite a bit of velocity compared to the W748 I was using.
I now use Benchmark in my 223 - it meters great, doesn't overfill the case, has velocities that equal or exceed W748, and it's cleaner than Varget. I use Win. and R-P cases, WSR primers, and 50 gr. Speer TNT and Nosler Balistic tip bullets in my Ruger M77. The Noslers shoot a bit more accurate, but they also cost twice as much. I shoot 55 gr. Win FMJBT in my AR. All my loads are about 1 gr. under max according to the Hodgdon manual. I also shoot Benchmark vary well in my 125 gr. 308 loads, but Varget does better with the heavier bullets in 308.
