I have been using H1000 powder in my 338 RUM.
But would like to try RL25 but don't have any
reload info for the 250 gr bullet.I don't know if it can be used. Any reload info on RL25 is what I would like to know.
I have used up to 90 grains RL25 with the 300 SMK. You can probably start at around 86? for the 250. I like RL22 for the 250 though. Do a search--if I remember there is a member who goes by Guy (user name) who posted a bunch of data. Also there is data at www.accuratereloading.com --these guys really load em hot so be sure to work up.
