Berger's gyroscopic stability factor calculator using G7 puts your 143 at an SG of 1.0 where 1.5 is stable. A 1.12 for the 140 ELD M. Both have a suggested twist of 8. Berger is normally liberal with twist rates. Regretably I don't have any examples of the lighter bullets. Have you considered 100 grain options from Sierra and Nosler? 3000 fps sounds like a lazer.
