It comes down to what bullet and powder. I am loading A1680 and 220 grain bullets. Pretty easy to find a load. I am at altitude so Subsonic speed can differ from yours.

I ran 220 Out Law State with 10.0 grains of H110. But I want to try some Lil gun when I get back to shooting.

1680 is pretty much the standard for subs. I run 10.5-10.7 with 220s.

Thanks for that info. I wondered where to start. Do you use any filler?

No. Not needed with the 220gr bullet.

I'd start near 11 grains and work down.
