I cant tell you what the speed is, but I get real good accuracy, under 1/2", using 46.5gr H4350 and 120gr NBT in my .260 Rem.
H4350, one of my favorite powder's. What doesn't it shoot well in? Can't find any for quite a while. Just got my 260 and going to use RL-19 in it. Have had good luck with it. Have most of 2 jugs of it left. Sure miss my H4350 though!
