Cast bullets behave differently than jacketed ones, so you’ll probably have a hard time finding a cast bullet which resembles a jacketed one and still works ok. For higher velocities, you almost always need a gas check, but even then, I don’t think you will be able to push a .223 bullet to the same velocities as a jacketed one and still maintain accuracy. But I could be wrong too.
If you look at the 223 bullets, there are some around that weight, but the shape is different.

In his article “Reloading for the M1 Rifle, American Rifleman magazine, March 1986, John R. Clarke recommends:
Using Sierra 168 gr. HPBT match bullet not Nosler
Fed. 210 M primer
Lake City M brass46.5 gr. IMR 3031 – 2697 fps.
47.5 gr. IMR 4895 – 2676 fps.
48.5 gr. IMR 4064 – 2635 fps.
48.0 gr. H4895 – 2706 fps.
47.5 WW 748 – 2587 fps.You may have to tailor the load you use to your individual rifle; depending on wear factor in the gas system, etc., you may find that your own rifle likes a charge thats been increased a grain or a half-grain.
I shoot mostly 150-152 gr. bullets in my M-1 Rifles. Part of that has to do with my having a supply of pulled milsurp M-2 bullets, and part of it is because I tend to try to replicate service loads in my milsurp rifles. Many shooters find that they get increased accuracy from heavier bullets, specifically in the 173-180 gr. range. Its probably no accident that the service match bullet is 173 grains Army tech manual says 175.5, but thats close enough.
