I just seated them to match Factory OAL of 2.610 and out of a half dozen 3 shot groups none have broke out of 1/2 MOA with multiple powders.
They are fast! I stopped at 3740 as spin rate is getting up around 340,000 RPM.
Not sure how fast these can be spun but seems I remember mid to upper 300,000’s is where things get iffy.
