It would also be useful to know what velocity you were interested in achieving. If your cartridge is a .22-250, a 55 gr bullet at 3000 fps would be a reduced load. If on the other hand you want to get below 2000 fps, you will have to switch to a faster powder than one would normally use in the .22-250.
If you are loading for the .223, the same thing applies. The lightest loads with normal powders will make around 2500 fps with a 55 gr bullet.
I would add that bullets with longer bearing surfaces as a rule show better accuracy when loaded to velocities below 2000 fps. A spitzer boat tailed design tends to be a long bullet for weight, but the bearing surface, the surface that contacts the bore, is quite short. A flat base round nosed bullet of the same weight is shorter, but has a longer bearing surface.
