Yeah that is slow...
RE19 and if you can find it RE17 is the go once you get your reloading gear. I'm in Australia but I have found similar variations. The 300 wsm
responded to RE19 with 180gn pills very well. We even go over 3030fps using the 180gn TTSX Barnes . ADI 2209 ie has a hogdon equivalent which was also slow, so in the wsm stick with the Alliant range IMO. Not that I can get many any other makes down under!.
Very hard to beat Win factory velocity but you could try some Federal ammo?
