Range Report Desert Tactical Reloading Info needed

[ViperACR]

I just got my new DTS in 338LM and was wanting to know what other owners are using for data, and velocities you are getting? I have the 26" and I am not getting but about 2645-2700 fps with my somewhat typical load of 86-88 gn RL25 and 300gn SMK, Lapua virgin brass, that my other 338s like. Also the extream spreads are 50-90 with all loads tested. I have just spent a short time working with it but thought someone might have some inside info. Thanks in advance to all.

in my experience retumbo gave me less extreme spread than rl25 plus a little faster. might want to try it. ive used it in 300 weatherby and 375 cheytac both have had under 15 fps e.s.
