Getting the 270WSM ready

Is that BC with a 1:10? Litz knocked the 150 ABLR to .543 in a 1:10,not .625

The 70.0 gr retumbo is the group to chase. The rl22 group is bigger and unless the chrono was an oelher 35p or a magneto speed I wouldn't put any faith in the spreads. Let the targets tell the tale. Smaller group and way more velocity is the way to go imo.

S hrek, I completely agree with your philosophy but the only thing I might add for RL-22 is to try us 68.5 thru 70.0 when tweaking since there was minimal gain from 68.5 up "IF" the chrono was telling the truth (if you won't trust it why use it ?)
