My Remington likes WW748
I use 28.0 grs. of WW 748 with a CCI BR primer and Hornady brass in my Remington. I load 30gr. Bergers and they are deadly accurate with this combination. I cleaned out a field of gophers recently with the longest shots being 210 yards and this combination is dead on.
Frankly, I thought Varget would be better but WW 748 has proven to be the best so far. I bought an 8 pound canister of it recently, mainly for 5.56, so it works out much cheaper as well.
BTW, the Hornady 32 gr. VMax works quite well (in my gun anyway) with the same load.
