Don't know about a 22/250 but for 223, N140 is good for bullets of 60gr or heavier, but a little too slow burning for anything much lighter where N133 makes a better choice. I use N140 for 69gr 223's (which print ragged one hole groups) and N133 for 60gr V-max and 55gr SGK. Get much better velocities for a lower charge with the N133 and no compression of the load.
