    Reliant 25 load data for 338 lapua

    Anyone out there loading with rl25? I need some load data for rl25 for a 300 grain Berger. Have 5 lbs of it. Any help would be appreciated.

    I put together some of these with new lapua brass and cci primers. I found somewhere that said the spread on powder charge was 80 to 92 grains and I loaded them with 85 grains. I have a savage 110 ba and used these to start to break in the barrel. After fifty rounds I could keep 5 round groups at 100 yards with all rounds touching making one big hole usually. I didn't have any problems with my brass sticking in any way. I'm waiting to get a neck sizing die to reload them with to see how they do the second time around. I'm very new to reloading (only started last summer) so I don't know much. I'm going to a sniper school at the end of the month that has a 1000 yard range and hope to see how well this set up does. hope this helps.

    I use RL-25 for my 338LM. I settled on it after using 4 other powders. My 300gr SMK load is 90gr with Fed 215 primers and Lapua brass. As always, start low and work up.
    If you are not living on the edge, you are taking up too much space!!!!!!
