my apologies.....my Lyman manual lists the H-380 all the way to 170 grain bullets.

My Hodgdon manual only lists it for the 100 grain bullet and then it' s in 7th place for performance. (Basic reloaders manual 2000)

The performance powders for the .270 are IMR 4831, H-4831,RL 19, RL 22,

Sorry, I' ll do a little more checking next time.....but the H-380 still isn' t a good powder for the .270
