Yeah, Roskoe has a good bullet mentioned. I have heard from many sources that the nosler is a great choice. As far as the 47 grains, I cant really say. I use 40 grains of 4350 for a 100 grian bullet and I get 2900 fps out of it. Plenty good performance by my estimation. But just keep in mind that at higher velocities your need for a bullet that can retain weight becomes greater which leaves you with the choices of bonded bullets or the partitions, of which there are ample choices.
