    I have had trouble finding charts that are inclusive of powders like Retumbo for the 180 Accubond in the .300 RUM. Being new to reloading I don't want to stray from published data. Is this the powder I should be looking towards? I am looking for all weather long range consistency. What else should I try powder-wise?

    I loaded A LOT of H1000 and a little Retumbo. Both worked well, but my rifle liked H1000 a bit better.

    Have had the best luck with RL-25 with the 180 AB's. Both my 300 RUM's loved RL-25, espescially with the 180 AB's. Both shot 1/4 MOA regularly with that combo. I say regularly because it wasnt always 1/4 minute. Still, even the bad groups were good groups. Good velocity to boot. I didnt find it to be nearly as temp sensitive as some claim either. Actually, it was pretty minimal.

    I have used all the powders mentioned and they all worked well,i also found h4831 very accurate with accubonds in my sendero,fps was down a little compared to RL25 & H1000.

    I also had the best luck with RL-25. Very consistent velocity and group size.

    I never tried the 180 Accubonds in mine, but Retumbo was the go to powder with 190 SMK's.

    I'll throw in here to use Fed 215s with the slower powders. I've seen drastic velocity spreads with CCI 250s combined with RL 25 that went away using the 215s. I also got a velocity gain of nearly 50 fps (no pressure signs) to go along with the change of primers and (obviously) the groups were better.
