Took my M70 Laredo out to the range yesterday and she is looking promising. I am going to try some RL25 next.

I have some 140gr, and will try them next. The amazing thing is that both bullets hit almost exactly the same location on the target. Nice consistency. I have a 4.5-14 Burris FF II mounted on it.
Forgot my chrony, so no velocity numbers to report. Will make sure to take it next time though.
 
The H-1000 did not shoot much better than US869. I load mine to 3.600" OAL.
I will try some Retumbo and RL25 next and maybe even some 7828. I did chrono the 90grs of US869 and the 160gr TSX and they averaged 3090fps for three shots.

What charge weight of Retumbo should I start at with the 160gr AB?

That's about what I had for 90 gr. of US869....nothing outstanding but fairly accurate. I think it was MTM on here that was using 7828 with 160's . I think it was for better than 3200 fps but I cant remember that far back.
 
I know you want to use the slowest powders but in my 3 STWs to date 7828 has been the best with 160 anything. I've used the same load for ever, PM me for details. 160 TSXs at very close to 3300 outa 24"s.
