.338 RUM 225gr TTSX powder question

[mtmuley]

Hi guys, I haven't posted in awhile, but I need some info. I'm loading a friends .338 RUM with a 225gr TTSX and getting great results with Retumbo. I'm not at Barnes' max, but velocity seems slow for the load. I'm thinking the data is conservative. RL-22 attains higher velocity, but not great accuracy so far. I'm not at max with it either. Now, I want to try RL-25. I have a start load in mind. I'd sure like to know what any of you have found loading any of these powders in the .338 RUM. Thanks, mtmuley

I shoot a 225 accubond in front of 97 gr of rl 25 with great results. This is a max load and vel is 3300 out of my 27 inch broughton barrel
