If you want to get something more suitable for .223Rem than Vihtavuori N140, there are a couple of us here who would delight in taking it off you in return only for money.

Well according to Vihtavouhri it's not a bad choice giving as good if not better velocity for 55 gr bullets than the other powders they list, works well under 69grainers too

I ran out of varget so carried on using n140 in my 223. Very similar burn ratios on some comparison charts. It shot very accurately & made a noise, but was not the most efficient powder for the bullet weight I was using (53s). I now am on n133 in the 223 & keep the n140 for the 308. I get more velocity from less powder in the 223 now.

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.

I hear what you're saying but a better case fill or even a compressed load from a higher charge can surely lead to more consistency as there's less space for the propellant to move around differently? Don't know.

I use it under 69 gr TMKs too, for 52/55 gr bullets I use TAC and for 40s I use exterminator. May have to change that soon though as no one knows when any is coming in!
