Trail Boss (if you can find some): examples
223, 55 gr pill, 4 gr powder => 1003 fps (an expensive 22LR!)
With Trail Boss, it won't over-pressure.
The other end is the problem, under-pressure where pill gets stuck in the barrel.
With Trail Boss, starting loads are high (supersonic)and work down to subsonic.
Subsonic loads hit a couple feet low at 100 yards vs laser loads, fwiw...
.... rule #9 ....
