I've never checked the speed but it makes a pretty clover leaf at 100 yds and at 200 when I'm shooting good. It stomped a big South Dakota muley at 275 yds in 2009.
My .270 shoots 150gr. Partitions extremely well. It's a 700 BDL and I use 59 grains of Hodgdon H4831sc, Nosler brass, and CCI large rifle primers. It's my favorite .270 load for deer.
